concurring.

As fully set forth in Commonwealth v. Polimeni, 474 Pa. 430, 378 A.2d 1189 (1977) (opinion by Pomeroy, J., joined by Eagen, C. J., announcing the decision of the Court), decided this day, the Crimes Code1 has made “[a]ll grades of unlawful killing lesser included offenses of the overall crime of criminal homicide.” It was there stated that “because the legislature [in the Crimes Code] has classified both murder and involuntary manslaughter as subdivisions of the major offense of criminal homicide, a defendant who has been charged with murder is entitled on request to have the jury instructed on the elements of involuntary manslaughter at least where evidence is presented at his trial on which a verdict of that less serious offense could rationally be based.” Ibid. 474 at 430, 378 A.2d at 1189.

In the case at bar, as in Commonwealth v. Polimeni, supra, and Commonwealth v. Ford, 472 Pa. 542, 372 A.2d 821 (1977), also decided this date, a jury could rationally have found the appellant guilty of involuntary manslaughter on the evidence presented;2 thus I agree that the trial court should have granted appellant’s request to have the jury instructed on involuntary manslaughter, and that a new trial is required because this was not done. I thus concur in the mandate of the plurality opinion. As in Polimeni, supra, and Ford, supra, however, there is here no need to reach, as the plurality does, the question whether a defendant being tried for murder is entitled on request to an involuntary manslaughter charge regardless of the evidence presented to the jury. As Mr. Justice Roberts stated in Commonwealth v. Moore, 463 Pa. 317, 328, 344 A.2d 850, 856 (1975), “[we] need not decide whether rationality should be a requirement for a permissible verdict, for in this case, a verdict of involuntary *471manslaughter would have been rational.” (Concurring opinion of Roberts, J.) (footnote omitted). Moreover, no such broad claim is made by appellant, and the point was neither briefed nor argued by either party in this Court.

OPINION

Appellant Bennie Garcia was arrested on March 1, 1974, and charged with murder and voluntary manslaughter. At trial, appellant requested a jury instruction on involuntary manslaughter. The court refused his request because (1) appellant had not been indicted for involuntary manslaughter, and (2) in the court’s view the evidence of involuntary manslaughter was “at best meager and feeble.” The jury returned a verdict of guilty of voluntary manslaughter and the court, after denying post-trial motions, imposed a sentence of five to ten years imprisonment. In this appeal,1 appellant contends that the court erred in refusing his *454requested instruction on involuntary manslaughter. We agree, reverse the judgment of sentence and remand for a new trial.2

I

At approximately 8:30 p.m., February 2, 1974, appellant, his brother, and three friends visited a tavern several miles from appellant’s home. They had never been to the tavern before and did not know any of the patrons. Appellant was carrying a pistol tucked under his belt when he entered the tavern.

At approximately 1:00 a.m., a fight broke out in the men’s room between appellant’s brother and several other patrons of the tavern. Appellant rushed towards the men’s room. As he entered the doorway to the men’s room, appellant was pushed back by the victim.

There is conflicting testimony concerning what happened next. The Commonwealth’s witnesses testified that appellant drew his pistol and shot the victim while they were a few feet apart. Appellant testified that he went back into the men’s room to look for his brother, and the victim grabbed him by the hair and yanked his head down. Appellant claimed that he was hit several times as he struggled to get free, and that the pistol fell out from under his belt. He testified that, while the victim still held him, he picked up the pistol and it accidentally discharged. Appellant stated that he did not intend to fire the pistol.

II

The general rule in Pennsylvania is that on an indictment charging a particular offense the defendant may be convicted of a lesser offense which is included within the crime charged. Commonwealth v. Soudani, 398 Pa. 546, 547 n.l, 159 A.2d 687, 688 n.l (per curiam), cert. denied, 364 U.S. 886, 81 S.Ct. 177, 5 L.Ed.2d 107 (1960); Commonwealth v. *455Parker, 146 Pa. 343, 344, 23 A. 323 (1892) (per curiam); Commonwealth v. Lewis, 140 Pa. 561, 21 A. 501 (1891); Hunter v. Commonwealth, 79 Pa. 503, 506 (1875) (“The general rule is well settled that upon an indictment charging a particular crime, the defendant may be convicted of a lesser offense included within it.”); Dinkey v. Commonwealth, 17 Pa. 126, 129 (1851); accord, Fed.R.Crim.P. 31(c) (“The defendant may be found guilty of an offense necessarily included in the offense charged . . .”).2a In our previous cases, however, this Court has not considered whether involuntary manslaughter is a lesser included offense of murder in determining whether involuntary manslaughter instructions should be given in a murder trial. See Commonwealth v. Hoffman, 439 Pa. 348, 357, 266 A.2d 726, 731 (1970); Commonwealth v. Reid, 432 Pa. 319, 322, 247 A.2d 783, 785 (1968); Commonwealth v. Hardy, 347 Pa. 551, 554, 32 A.2d 767, 768 (1943). Rather, these cases were predicated on a doctrine established in Commonwealth v. Gable, 7 Serg. & R. 423 (Pa. 1821), that involuntary manslaughter is never a permissible verdict on a murder indictment.

In Gable, the defendant was indicted for murder, but the jury returned a verdict of “not guilty of murder but guilty *456of manslaughter.” On appeal, the defendant argued that the verdict was void for uncertainty because it did not specify whether he was guilty of voluntary manslaughter or involuntary manslaughter. This Court held that the verdict was not uncertain. After pointing out that murder is a felony and involuntary manslaughter is a misdemeanor, the Court reasoned:

“[0]ne who is indicted for murder, cannot be convicted of involuntary manslaughter, because it is well settled, that there cannot be a conviction of a misdemeanor, on an indictment for felony. Therefore, when on an indictment for murder, the jury find that the defendant is guilty of manslaughter, it must be understood, such manslaughter as is felonious, which can be no other than voluntary manslaughter.”

7 Serg. & R. at 424; accord, Walters v. Commonwealth, 44 Pa. 135 (1863).

The rationale of Gable was rejected in Hunter v. Commonwealth, 79 Pa. 503 (1875). In Hunter, the defendant was indicted for assault with intent to kill, a felony, but the jury found him guilty of assault, a misdemeanor. The defendant argued that he could not be convicted of a misdemeanor on a felony indictment. The Court rejected this contention, reasoning that the common law rule relied on in Gable was based upon the different procedures employed at common law in felony and misdemeanor trials. Since the difference had long since disappeared in Pennsylvania, the Court observed that “[i]t is clear that the reason of the rule has no application in this state.” 79 Pa. at 505. The Court held “that the old common-law rule, that upon an indictment for a felony there can be no conviction for a misdemeanor, no longer exists in Pennsylvania.” 79 Pa. at 509.

The Court inexplicably reverted to the doctrine that involuntary manslaughter was not a permissible verdict on a murder indictment, without rejecting or distinguishing Hunter, in Hilands v. Commonwealth, 114 Pa. 372, 6 A. 267 *457(1886).3 After Hilands was acquitted of murder, he was indicted for involuntary manslaughter. On appeal from his conviction for involuntary manslaughter, this Court rejected Hiland’s claim that the trial for involuntary manslaughter violated the double jeopardy clause:

“It is very evident [appellant] can never be tried again upon any charge of which he might have been convicted upon the first indictment. .

“But the protection extends no further than the offence charged in the first indictment, or of which might have been convicted under it. He was not in jeopardy for any other offence. The first indictment charged murder. Under it he might have been convicted of murder of the first or second degree, or of voluntary manslaughter, but not of involuntary manslaughter. The latter offence is a misdemeanor; it must be charged as such, and cannot be included in an indictment charging felonious homicide .. It follows that when [appellant] was put upon this trial for murder, he was placed in no jeopardy of a conviction for involuntary manslaughter.”

114 Pa. at 380-81, 6 A. at 268.

Since Hilands, this Court has regularly held that involuntary manslaughter is not a permissible verdict on a murder indictment. See Commonwealth v. Jackson, 450 Pa. 417, 419 n.2, 299 A.2d 209, 210 n.2 (1973); Commonwealth v. Hoffman, 439 Pa. 348, 357, 266 A.2d 726, 731 (1970); Commonwealth v. Reid, 432 Pa. 319, 322, 247 A.2d 783, 785 (1968); Commonwealth v. Edwards, 431 Pa. 44, 52, 244 A.2d 683, 687 (1968); Commonwealth v. Soudani, 398 Pa. 546, 547 n.l, 159 A.2d 687, 688 n.l (dictum), cert. denied, 364 U.S. 886, 81 S.Ct. 177, 5 L.Ed,2d 107 (1960); Commonwealth v. Comber, 374 Pa. 570, 573-74, 97 A.2d 343, 344 (1953) (dictum); Common*458wealth v. Palermo, 368 Pa. 28, 31-32, 81 A.2d 540, 541-542 (1951); Commonwealth v. Hardy, 347 Pa. 551, 554, 32 A.2d 767, 768 (1943); Commonwealth v. Mayberry, 290 Pa. 195, 199, 138 A. 686, 688 (1927). But see Commonwealth v. Jones, 452 Pa. 569, 578, 308 A.2d 598, 604 (1973) (implying that involuntary manslaughter may be a permissible verdict if the facts presented by either side would support such a verdict); Commonwealth v. Robinson, 452 Pa. 316, 326, 305 A.2d 354, 359 (1973) (same). This Court never sought to justify the rule by analyzing whether involuntary manslaughter is a lesser included offense of murder. Some cases sought to support the rule by exhuming the corpse of the common law rule that a misdemeanor is not a permissible verdict on a felony indictment. See e. g., Commonwealth v. Comber, 374 Pa. 570, 580, 97 A.2d 343, 347 (1953) (dictum). Other cases simply restated the rule. Thus, this Court stated in Commonwealth v. Palermo, 368 Pa. 28, 31-32, 81 A.2d 540, 541 (1951): “It is still the law since Commonwealth v. Gable, 7 Serg. & R. 423 (1821) that . . . involuntary manslaughter which is a misdemeanor cannot be charged in an indictment with murder which is a felony.”

The doctrine that involuntary manslaughter is not a permissible verdict on a murder indictment has been weakened by the adoption of Pa.R.Crim.P. 219(a), which became effective in 1965. Pa.R.Crim.P. 219(a) provides: “Where murder is alleged in an indictment, no other counts may be joined in the indictment except voluntary and involuntary manslaughter.” Because involuntary manslaughter can now be charged in a murder indictment, it is questionable whether the doctrine established in Commonwealth v. Gable, 7 Serg. & R. 423 (Pa. 1821), should still bar application of the lesser included offense doctrine when an involuntary manslaughter instruction is requested in a murder trial. But see Commonwealth v. Reid, 432 Pa. 319, 247 A.2d 783 (1968).

The continuing validity of the doctrine that involuntary manslaughter is hot a permissible verdict on a murder indictment is also brought into question by our decision in Commonwealth v. Moore, 463 Pa. 317, 344 A.2d 850 (1975). *459Moore was indicted for murder and voluntary manslaughter and, in a separate indictment, charged with involuntary manslaughter. Moore’s petition to consolidate the indictments was denied, and the case was tried solely on the indictment for murder and voluntary manslaughter. At trial, Moore’s request for a jury instruction on involuntary manslaughter was denied. On appeal, Mr. Justice (now Chief Justice) Eagen, speaking for himself and Mr. Justice O’Brien, stated that a motion to consolidate an involuntary manslaughter indictment must be granted when there is evidence to support an involuntary manslaughter verdict. Id. 463 Pa. at 320,344 A.2d at 853 (plurality opinion) Mr. Justice Pomeroy, Mr. Justice Manderino, and this writer filed separate concurring opinions. Mr. Justice Pomeroy and Mr. Justice Manderino both agreed that the indictments should be consolidated); see Commonwealth v. Stock, 463 Pa. 547, 345 A.2d 654 (1975). The plurality reasoned that failure to consolidate the indictments was prejudicial error because it led to the refusal to instruct the jury on involuntary manslaughter. Commonwealth v. Moore, 463 Pa. at 322, 344 A.2d at 852-53 (plurality opinion of Eagen, J.); accord Commonwealth v. Stock, 463 Pa. 547, 551, 345 A.2d 654, 656 (plurality opinion of Eagen, J.); see Commonwealth v. Thomas, 403 Pa. 553, 170 A.2d 112 (1961). This writer and Mr. Justice Pomeroy stated that it would be error to refuse the instruction on involuntary manslaughter even if there had been no indictment for involuntary manslaughter. Commonwealth v. Moore, 463 Pa. at 323, 344 A.2d at 853 (concurring opinion of this writer); id. 463 Pa. at 336, 344 A.2d at 860 (concurring opinion of Pomeroy, J.).

Moore’s trial was not governed by the new Crimes Code, 18 Pa.C.S.A. §§ 101 et seq. (1973). The Crimes Code has removed any validity the doctrine that involuntary manslaughter is not a permissible verdict on a murder indictment may have had after Moore. Under the Crimes Code, murder, voluntary manslaughter, and involuntary manslaughter are all classifications of a single offense — criminal *460homicide. 18 Pa.C.S.A. § 2501.4 The common law doctrine that involuntary manslaughter is not a permissible verdict on a murder indictment, based on the classification of murder as a felony and involuntary manslaughter as a misdemeanor, cannot stand in view of the classification made by the Crimes Code. The common law doctrine has no continuing validity.

Accordingly, the determination whether jury instructions on involuntary manslaughter should be given in a murder trial must be based on the classification made by the Crimes Code, and upon an examination of whether involuntary manslaughter is a lesser included offense of murder.

Ill

Although a defendant generally may be convicted of an offense which is less than, but included within, the offense charged, there is no Pennsylvania statute, rule, or case which adequately sets forth the standards for determining what is a lesser included offense. In determining whether involuntary manslaughter is a lesser included offense of murder, we are guided by Section 1.07(4) of the American Law Institute’s Model Penal Code. This section provides:

“A defendant may be convicted of an offense included in an offense charged in the indictment or the information. An offense is so included when:

(a) it is established by proof of the same or less than all the facts required to establish the commission of the offense charged; or

(b) it consists of an attempt or solicitation to commit the offense charged or to commit an offense otherwise included therein; or

(c) it differs from the offense charged only in the respect that a less serious injury or risk of injury to the *461same person, property or public interest or a lesser kind of culpability suffices to establish its commission.”5

Applying this standard, we determine that involuntary manslaughter is a lesser included offense of murder.

Under the Crimes Code, murder, voluntary manslaughter, and involuntary manslaughter are all classifications of the crime of criminal homicide. 18 Pa.C.S.A. § 2501 (1973) provides:

“Criminal Homicide

(a) Offense defined. — A person is guilty of criminal homicide if he intentionally[6] knowingly/[7] recklessly[8] or *462negligently[9] causes the death of another human being.

(b) Classification. — Criminal homicide shall be classified as murder, voluntary manslaughter, or involuntary manslaughter.”

The essential element necessary to sustain a murder conviction, which distinguishes murder from involuntary manslaughter,10 is the state of mind of malice. See Commonwealth v. Thompson, 466 Pa. 15, 351 A.2d 280 (1976); Commonwealth v. Boyd, 461 Pa. 17, 334 A.2d 610 (1975).11

*463Absent circumstances which would mitigate the offense to voluntary manslaughter12 a criminal homicide is committed with malice if it is committed with an intent to kill. See Commonwealth v. Butcher, 451 Pa. 359, 364, 304 A.2d 150, 153 (1973). A criminal homicide constitutes involuntary manslaughter if it is committed recklessly or with gross negligence. 18 Pa.C.S.A. § 2504 (1973). Thus, when malice is based on an intent to kill, the recklessness or gross negligence which would support an involuntary manslaughter conviction constitutes a “lesser kind of culpability,” Model Penal Code § 1.07(4)(c), than the malice necessary to support a murder conviction.

Malice may also be found if, in killing another, the defendant “consciously disregarded an unjustified and extremely high risk that his actions might cause death or serious bodily harm . . . .” Commonwealth v. Taylor, 461 Pa. 557, 565-66, 337 A.2d 545, 549 (1975) (opinion of this writer, joined by Jones, C. J., and Eagen and Manderino, JJ.); accord Commonwealth v. Boyd, 461 Pa. 17, 22-23, 334 A.2d 610, 613 (1975).13 The recklessness or criminal negligence necessary to support an involuntary manslaughter conviction may be found if the defendant consciously disregards or, in gross deviation from a standard of reasonable care, fails to perceive a substantial and unjustifiable risk that his action might cause death or serious bodily injury. *464See 18 Pa.C.S.A. §§ 302(b)(8), 302(b)(4), 2504 (1973). It follows that when malice is based on the disregard of an extremely high risk of death or serious bodily harm involuntary manslaughter is a lesser included offense of murder in two respects. First, a “less serious . . . risk of injury . suffices to establish its commission.” Model Penal Code § 1.07(4). The evidence may persuade the jury that the defendant is guilty of murder in all respects except that the risk disregarded was not extremely high, but that the risk was still unjustified and that therefore the killing constitutes involuntary manslaughter. Second, “a lesser kind of culpability suffices to establish its commission.” Id. The evidence may persuade the jury that the defendant did not commit murder, because the defendant did not perceive the risk to others, but that the defendant should have perceived the risk to others, and therefore committed involuntary manslaughter. See Survey of Pennsylvania Law, 38 U.PittL.Rev. 185, 263 n.92 (1976).

We are convinced, therefore, that the state of mind which suffices to establish the commission of involuntary manslaughter constitutes a lesser kind of culpability than the malice which is an essential element of murder.14 We conclude that involuntary manslaughter is a lesser included offense of murder.

*465Moreover, an examination of the Crimes Code convinces us that whenever the evidence would support a verdict of murder or voluntary manslaughter, it is also sufficient to support a verdict of involuntary manslaughter. Murder and voluntary manslaughter are classifications of criminal homicide. 18 Pa.C.S.A. § 2501(b) (1973). A criminal homicide has been committed when a person “intentionally, knowingly, recklessly, or negligently causes the death of another human being.” Id. § 2501(a). The Crimes Code also provides: “When the law provides that negligence suffices to establish an element of an offense, such element is also established if the person acts intentionally or knowingly.” Id. § 302(e). Therefore involuntary manslaughter, which is defined as a killing committed in a reckless or grossly negligent manner, id. § 2504, also may be committed when a killing is committed intentionally or knowingly. Under the Crimes Code the categories of murder and voluntary manslaughter on the one hand, and involuntary manslaughter on the other, are not mutually exclusive categories. Because an intentional or knowing killing also establishes a negligent killing, all criminal homicides necessarily include involuntary manslaughter as a constituent offense.15

IV

[II] Because involuntary manslaughter is a lesser included offense of murder, and because the evidence would support an involuntary manslaughter verdict whenever it would support a murder or voluntary manslaughter verdict, a defendant should be entitled to a requested instruction on involuntary manslaughter in all criminal homicide prosecutions. Allowing the jury to decide the case without ade*466quate instruction as to the permissible verdict of involuntary-manslaughter denies the jury information essential to a fair determination of the case. As Mr. Justice (now Chief Justice) Eagen has stated:

“In those instances where an involuntary manslaughter verdict would be supported by the evidence, the failure to so acquaint the jury prevents it from operating with full knowledge of the relevant law and precludes the defendant from having a fair trial.”

Commonwealth v. Moore, 463 Pa. 317, 322, 344 A.2d 850, 853 (1975) (plurality opinion).

The need for an instruction on involuntary manslaughter also follows from the Commonwealth’s burden of proof. The United States Constitution requires the Commonwealth to prove every element of the offense, including the degree of culpability, beyond a reasonable doubt. In re Winship, 397 U.S. 358, 90 S.Ct. 1068, 25 L.Ed.2d 368 (1970). Thus, in any case in which the evidence would be sufficient to sustain a verdict of murder or voluntary manslaughter, the jury might conclude that the Commonwealth failed to meet its burden of proving malice, intent, or knowledge, but has proven recklessness or negligence.

In order to avoid the possibility that the jury will erroneously convict the defendant of murder or voluntary manslaughter, when only involuntary manslaughter has been proven, a jury instruction on involuntary manslaughter must be given. It is no answer that if the evidence proves involuntary manslaughter only, and no instruction on involuntary manslaughter is given, the jury should acquit:

“True, if the prosecution has not established beyond a reasonable doubt every element of the offense charged, and if no lesser offense instruction is offered, the jury must as a theoretical matter, return a verdict of acquittal. But the defendant is entitled to a lesser offense instruction — in this context or any other — precisely because he should not be exposed to the substantial risk that the jury’s practice will diverge from theory. Where one of the elements of the offense charged remains in doubt, but *467the defendant is plainly guilty of some offense, the jury is likely to resolve its doubts in favor of conviction.”

Keeble v. United States, 412 U.S. 205, 212-13, 93 S.Ct. 1993, 1997-98, 36 L.Ed.2d 844 (1973) (emphasis in original); see Commonwealth v. Thomas, 403 Pa. 553, 170 A.2d 112 (1961). The jury should not be forced to choose between a murder or voluntary manslaughter verdict and an acquittal when, properly instructed, the jury would find the defendant guilty of involuntary manslaughter.

It has been argued that an instruction on involuntary manslaughter should not be given in a murder trial because it might confuse the jury. See Commonwealth v. Nace, 222 Pa.Super. 329, 331, 295 A.2d 87, 88 (1972) (dictum); cf. Commonwealth v. Comber, 374 Pa. 570, 578, 97 A.2d 343, 346-47 (1953) (assault and battery instruction, on a murder indictment, might confuse the jury). We are not convinced that an instruction on involuntary manslaughter presents a serious risk of confusing the jury. Indeed, in many cases, it will help to clarify the issues by giving the jury “full knowledge of the relevant law.” Commonwealth v. Moore, 463 Pa. 317, 322, 344 A.2d 850, 853 (1975) (plurality opinion). The possibility of jury confusion in some cases is not an adequate ground to justify the unfairness of denying a requested instruction on involuntary manslaughter.

A conclusion that an involuntary manslaughter instruction would only confuse the jury is necessarily based on the assumption that, given the evidence presented in the case, it would be wrong to reach such a verdict. If the evidence proves involuntary manslaughter, and not voluntary manslaughter or murder, it cannot be said that it would confuse the jury to give an involuntary manslaughter instruction. But the issue whether the evidence proves involuntary manslaughter, and not voluntary manslaughter or murder, is for the jury to decide. It is the province of the jury to weigh the evidence, and the jury is entitled to believe all, part, or none of the evidence presented. Commonwealth v. Kahley, 467 Pa. 272, 356 A.2d 745 (1976); Commonwealth v. Rose, 463 Pa. 264, 344 A.2d 824 (1975); Commonwealth v. Wright, 458 Pa. 236, 328 A.2d 514 (1974).

*468The jury’s province to weigh the evidence includes the right to believe all, part of, or none of the testimony of a particular witness. Commonwealth v. Marlin, 452 Pa. 380, 305 A.2d 14 (1973); Commonwealth v. Oates, 448 Pa. 486, 295 A.2d 337 (1972); Commonwealth v. Petrisko, 442 Pa. 575, 275 A.2d 46 (1971). Thus it is not grounds to deny an involuntary manslaughter instruction that the Commonwealth’s evidence, if believed, would prove murder or manslaughter, and the defendant’s testimony, if believed in its entirety, would require a verdict of not guilty. As Chief Judge Bazelon stated in Broughman v. United States, 124 U.S.App.D.C. 54, 55, 361 F.2d 71, 72 (1966) (footnote omitted), quoting Young v. United States, 114 U.S.App.D.C. 42, 43, 309 F.2d 662, 663 (1962) (emphasis in Broughman):

“The fact that [the witness’] testimony raised an issue whether appellant was guilty of any crime at all is not inconsistent with appellant’s claim that this same testimony raised an issue whether a lesser included offense had been committed. Nor would the jury have to credit all of [the witness’] testimony. In Young v. United States, we held: ‘. . .it would be permissible for the jury to totally disbelieve . . . [the witness] or to believe that part which tended to exculpate appellant from an intent to [commit the greater offense.]’ ”

The jury is not bound by any witness, or by any particular theory of the case.16

*469Involuntary manslaughter is a lesser included of-' fense of murder, and if the evidence is sufficient to allow the jury to consider a murder verdict it is sufficient to allow the jury to consider an involuntary manslaughter verdict. Neither the prosecution’s theory of the case, nor the court’s evaluation of the weight or credibility of the evidence, should deprive the jury of the information necessary to consider whether involuntary manslaughter has been committed. Therefore we hold that in every murder prosecution a defendant is entitled, upon request, to a jury instruction on involuntary manslaughter.

At appellant’s trial, his requested instruction on involuntary manslaughter was denied. Allowing the jury to decide this case without an instruction on involuntary manslaughter deprived appellant of a fair trial. Judgment of sentence reversed and a new trial granted.

dissenting.

The issue raised in this appeal is whether an individual charged with murder and voluntary manslaughter has a right to have the jury consider the charge of involuntary manslaughter as a possible verdict. The majority concludes that a defendant should be entitled to a requested instruction on involuntary manslaughter in all criminal homicide prosecutions. Not only do I believe that the result reached is most unwise and will ultimately do a great disservice to the law of this jurisdiction, I am equally convinced that the reasoning employed by the majority to reach its conclusion is unsound. Hence this dissent.

This appeal provided a unique opportunity to reconsider, in light of our new penal code,1 the troublesome problems of the permissible verdicts in a homicide prosecution. Rather than seizing upon this opportunity to consider the area afresh, the majority has persisted in attempting to incorporate a principle relied upon in the past which, in large measure, created the problems which we have been, up to this point, unsuccessfully struggling to resolve.

Specifically, I refer to the majority’s reliance upon the lesser included offenses analysis for the basis of its determination as to whether or not a jury instruction, requested by the defense, must be given in a given case. While I do not wish to deprecate the utility of the general concept of lesser included offenses in some areas of the criminal law,21 do not believe the jurisprudence of this jurisdiction is advanced by *472attempting to analyze the question presently before us in such a framework. The legitimacy of this analysis, particularly as it has been applied to homicide cases, is at least suspect and its applicability in the past has proven troublesome.3

The first articulation of this concept by this Court appears in our decision in Dinkey v. Commonwealth, 17 Pa. 126, 129 (1851). There the Court was confronted with the question of successive prosecutions. The Court reasoned that since the accused, under an indictment for seduction might have been convicted of, and punished for fornication, he could not be subsequently tried for fornication after an acquittal under the seduction indictment. Thus, the Court sustained the plea of autrefois acquit and dismissed the indictment for fornication. It is interesting to note that this Court has since realized that the common law pleas of autrefois acquit and autrefois convict, both of these pleas being but a corollary of the lesser or constituent offense concept, was inadequate to protect Pennsylvania residents against successive prosecutions and under its supervisory power opted instead to embrace the “criminal episode” concept to determine when future prosecutions would be barred. Commonwealth v. Campana, 452 Pa. 233, 304 A.2d 432, vacated and remanded, 414 U.S. 808, 94 S.Ct. 73, 38 L.Ed.2d 44, 455 Pa. 622, 314 A.2d 854, cert. denied, 417 U.S. 969, 94 S.Ct. 3172, 41 L.Ed.2d 1139 (1974).4 It is ironic that although we had no hesitancy when recognizing that the changing times had rendered the lesser included offense concept inadequate for a resolution *473of the problems presented by the question of successive prosecutions, even though the doctrine was first relied upon in this Commonwealth in that context, the majority inexplicably refuses to depart from that doctrine in the consideration of the instant question.

The problems with the use of a lesser included offense analysis has been further exacerbated because the concept was not confined to offenses necessarily included in the greater.5

“Both adultery and rape include the offence of fornication; it is necessarily involved in them: bastardy is not necessarily involved, but it may be.” Commonwealth v. Lewis, 140 Pa. 561, 564, 21 A. 501, 502 (1891) (Emphasis added).

This has been particularly true when applying the analysis to the law of homicides where the crimes have as a material element a particular result, i. e., the death of the victim. In approaching this area, our cases have treated the unlawful killing as the essence of all unlawful homicides and the manner of its commission merely as a circumstance.6 Superimposing the lesser included offense rationale upon this *474premise our cases mechanistically concluded that voluntary manslaughter was a lesser included offense of murder. Commonwealth v. Kellyon, 278 Pa. 59, 122 A. 166 (1923). This rationale which implicitly treats the distinction between a malicious killing and a non-malicious killing as being one of degree and not of kind is most difficult to reconcile with the many cases that have suggested the contrary:

“Murder is an unlawful killing of another person with malice aforethought, express or implied: Commonwealth v. Gooslin, 410 Pa. [285, 189 A.2d 157], supra; Commonwealth v. Carroll, 412 Pa. [525, 194 A.2d 911], supra, and numerous cases cited therein; Commonwealth v. Buzard, 365 Pa. 511, 76 A.2d 394. Malice express or implied is the hallmark, the criterion and the absolutely essential ingredient of murder.” (emphasis added). Commonwealth v. Kirkland, 413 Pa. 48, 63-4, 195 A.2d 338, 345 (1963).

See also Commonwealth v. Finnie, 415 Pa. 166, 202 A.2d 85 (1964); Commonwealth v. Carroll, 412 Pa. 525, 194 A.2d 911 (1963); Commonwealth v. Bolish, 381 Pa. 500, 113 A.2d 464 (1955); Commonwealth v. Kelly, 333 Pa. 280, 4 A.2d 805 (1939); Commonwealth v. Gibson, 275 Pa. 338, 119 A. 403 (1923); Commonwealth v. Drum, 58 Pa. 9 (1868) (“The distinguishing criterion of murder is malice aforethought.”).

Ignoring this inconsistency a more serious problem resulted because there are many instances where the facts of a case would justify a finding of murder but are at the same time devoid of the elements of provocation and passion sufficient to provide a “rational basis” for a voluntary manslaughter finding. While this would not have been an insoluble dilemma if we had been willing to confine the lesser included offense concept to those instances where the evidence did provide some basis for a finding of voluntary manslaughter, we failed to so restrict its application. To the contrary, the cases are legion which we have held that a conviction of manslaughter may be returned under a murder indictment even in the absence of provocation and passion if *475the record supports a finding of murder.7 See Commonwealth v. Hill, 444 Pa. 323, 281 A.2d 859 (1971); Commonwealth v. Hoffman, 439 Pa. 348, 266 A.2d 726 (1970); Commonwealth v. Harry, 437 Pa. 532, 264 A.2d 402 (1970); Commonwealth v. Dennis, 433 Pa. 525, 252 A.2d 671 (1969); Commonwealth v. Cooney, 431 Pa. 153, 244 A.2d 651 (1968); Commonwealth v. Pavillard, 421 Pa. 571, 220 A.2d 807 (1966); Commonwealth v. Frazier, 420 Pa. 209, 216 A.2d 337 (1966); Commonwealth v. Frazier, 411 Pa. 195, 191 A.2d 369 (1963); Commonwealth v. Moore, 398 Pa. 198, 157 A.2d 65 (1959); Commonwealth v. Nelson, 396 Pa. 359, 152 A.2d 913 (1959); Commonwealth v. Steele, 362 Pa. 427, 66 A.2d 825 (1949); Commonwealth v. Arcuroso, 283 Pa. 84, 128 A. 668 (1925); Commonwealth v. Kellyon, supra. An irreconcilable conflict was created when paralleled to the foregoing principle a rule emerged which provided that a trial court could refuse to instruct the jury of its power to return a verdict of voluntary manslaughter in cases where there was no rational basis for such a finding.8 Commonwealth v. Pavillard, supra; Commonwealth v. Dews, 429 Pa. 555, 239 A.2d 382 (1968); Commonwealth v. LaRue, 381 Pa. 113, 112 A.2d 362 (1955); Commonwealth v. Flax, 331 Pa. 145, 200 A. 632 (1938); Commonwealth v. Gelfi, 282 Pa. 434, 128 A. 77 (1925); Commonwealth v. Morrison, 266 Pa. 223, 109 A. 878 (1920); Commonwealth v. Russogulo, 263 Pa. 93, 106 A. 180 (1919); Commonwealth v. Sutton, 205 Pa. 605, 55 A. 781 *476(1903); Clark v. Commonwealth, 123 Pa. 555, 16 A. 795 (1889).

Even though we are faced today with the question as to when a requested charge as to involuntary manslaughter must be given, I have dealt at great length with the historical development of this problem as it related to voluntary manslaughter because I believe that it is instructive of the pitfalls that lie ahead if we insist upon viewing this question as one that must be resolved in the framework of the lesser included offense rationale. In the past, as the majority has noted, our courts declined to use the lesser included offense analysis in determining an accused’s right to an instruction for involuntary manslaughter. While I agree with the majority that the rule relied upon for rejection of the lesser included offense analysis has very little legitimacy in our law today, I nevertheless believe that the majority is in error when it recognizes the inappropriateness of one doctrine but is willing to accept another rationale equally as inappropriate. It is my basic thesis that the question presented is fundamentally one of practice and that we are not at this juncture bound by any constitutional or statutory restrictions in determining the approach that would most enhance the law of this Commonwealth.9 Having been freed from the strictures of the past by virtue of the enactment of the 1972 Code, it is my view that our responsibility should be to fashion the most desirable rule consistent with our concept of the respective roles of the court, prosecutor and jury, keeping in mind our judgment as to what is fair from the standpoint of the accused.

*477The majority suggests that the fact that the crimes code has set forth the generic crime of criminal homicide, 18 Pa.C.S.A. § 2501 (Supp. 1977-78), should be interpreted as an indication of a legislative intent to make involuntary manslaughter a permissible verdict in a murder prosecution. This fact, at best, is a neutral one since the new code also defines the various types of homicide, 18 Pa.C.S.A. §§ 2502, 2503, 2504 (Supp. 1977-78). To the contrary, there are factors which would suggest that the legislature did not intend to require a jury in a murder prosecution to consider all of the types of unlawful killings as a possible verdict.

First, under the 1939 Penal Code10 § 4701 expressly provided that the jury should decide the degree of murder.11 Conspicuously absent in the present code is any comparable language with regard either to murder, voluntary manslaughter or involuntary manslaughter. It is a fundamental rule of statutory construction that a change in language of a subsequent statute on the same subject may suggest a change in legislative intent. Haughey v. Dillon, 379 Pa. 1, 108 A.2d 69 (1954); Sekel v. Iagenemma, 170 Pa.Super. 621, 90 A.2d 587 (1952); Masland v. Bachman, 25 Pa.Cmwlth. 435, 361 A.2d 473 (1976); Nemitz v. Air Services International, 7 Pa.Cmwlth. 373, 298 A.2d 654 (1972). The omission of language similar to that used in § 4701 is a strong indication that the legislature, in enacting the new code, did not intend to require that a defendant should be permitted to have the jury consider all of the types of homicide in every murder prosecution.

*478Secondly, whereas the new crimes code does not provide a statute of limitation in murder prosecutions it does require that a prosecution for involuntary manslaughter must be commenced within two years after it is committed, 18 Pa.C. S.A. § 108 (Supp.1977-78). This is further indicative of the legislature’s recognition that there would be instances where a murder prosecution could be initiated yet the accused would be immune from prosecution for involuntary manslaughter. It is therefore clear, at least in those instances, that the legislature did not intend to confer upon the accused the substantive right to provide the jury with the option of returning an involuntary manslaughter verdict.

I am satisfied that there is no legislative mandate requiring the result reached by the majority. We therefore must now consider the wisdom of imposing such a procedural rule under our supervisory powers. Pa.Const., art. Y, § 10. I do not share the belief that the encouragement of compromise verdicts provides a salutary effect upon our jurisprudence.12 Further, I believe the fear that jurors will be reluctant to discharge their responsibilities with fidelity to be exaggerated. I reject the majority’s view that failure to instruct the jury as to the elements of involuntary manslaughter might contribute to the possibility of an erroneous conviction of the higher grade of the offense. As I stated in my dissent in Commonwealth v. Moore, 463 Pa. 317, 340, 344 A.2d 850, 862 (1975):

“I have a serious question as to the validity of the majority’s implicit assumption that the additional instructions to the jury as to the elements of involuntary manslaughter, while they are laboring under the onerous task of attempting to absorb the difficult distinctions between the other grades of homicide, will provide the jurors with an *479understanding of ‘the full significance of the law of homicide in Pennsylvania.’ It is more likely to make comprehension impossible.” (footnote omitted).

The charging decision is properly a prosecutorial function. See Commonwealth ex rel. Davis v. Reid, 338 Pa. 351, 12 A.2d 909 (1940); A.B.A. Standards on The Prosecution Function, §§ 3.5, 3.9 and Commentaries (approved draft 1971). See generally, Commonwealth ex rel. Specter v. Martin, 426 Pa. 102, 232 A.2d 729 (1967); Commonwealth ex rel. Specter v. Bauer, 437 Pa. 37, 261 A.2d 573 (1970). The prosecutor’s awareness of the strengths and the weaknesses of his case places him in the best possible position to assess whether a jury would be likely to reject a verdict of the higher grade of homicide under a given set of facts. I, therefore, suggest that the appropriate rule would be to give the option to the district attorney of charging all of the grades of criminal homicide or to permit him to select the specific charge or charges he deems appropriate under the evidence he intends to present.13 In the event that he chooses the latter course and the jury sees fit to acquit the accused, then under this Court’s decision in Commonwealth v. Campana, supra, subsequent prosecution for the offenses not initially charged, would be barred.14 Additionally, this approach would encourage responsible charging by the prosecutor and deter the “boiler-plate” charging of accused.

*480Accordingly, in the instant case, it is my view that the trial court did not err in denying the requested instruction for involuntary manslaughter and I would therefore affirm the judgment of sentence.
