The opinion of the court was delivered by

Defendants were convicted of second degree murder. The victim, Nathan “Dukie” Mitchell, was shot on a street in East Orange on February 16, 1972. With leave of the court, separate appeal briefs were filed for each defendant, and each asserts various errors in the trial judge’s instructions to the jury.

*480The State offered evidence tending to support a ease of felony murder. Alma “Dolly” Darci testified that she had given Dukie narcotics on credit; that shortly thereafter defendants approached Dukie, pushed him against a car and began going through his pockets. Dukie resisted and he was shot. She said that Gary Robinson had the gun, although there was testimony that Derek Van Austin had the gun earlier that evening.

Jimmy Johnson testified that he was with Alma Darci when he heard the shot. They were the State’s principal witnesses. Johnson testified that they were walking side by side, talking, and upon hearing the shot he turned around and saw Dukie fall. Then defendants ran past them. There was evidence that Johnson and Darci were close associates who dealt in narcotics and knew defendants before this incident.

Both defendants testified. Gary Robinson said that he spent the day with Derek Van Austin; that Derek had a gun which he tried to use as security for a loan from Jimmy Johnson so that they could both buy heroin, but Johnson declined the offer. Robinson said that he took the gun from Derek intending to use it in negotiating for heroin. He also testified that earlier in the week he had “burnt” Dukie by taking $35 from him for heroin without delivering the goods. He said he did not see Dukie again until the night in question. He testified that Dukie approached him in anger, an argument ensued and he stepped back, displaying part of the gun to Dukie to scare him off. Instead, Dukie reached for the gun, the gun went off and Dukie fell. He and Derek ran to Derek’s house. At that time Derek had the gun and Robinson arranged to have someone dispose of it.

Derek Van Austin testified that he was with Gary Robinson when Dukie approached in an angry manner. Robinson produced a pistol and Dukie grabbed for it. A struggle ensued, the gun went off and he ran from the scene. He said he did not join in the struggle and he denied having the *481gun that night. He admitted using heroin in small quantities. Both defendants denied that it was Dukie who was supposed to deliver heroin to them. The State theorized that it was defendants who expected to receive heroin from Dukie and that they went after him to seize the heroin that he had obtained from Alma Darci.

The trial judge charged the jury on various principles of law, including murder, manslaughter, malice, aiding and abetting, misadventure, self-defense and the duty to retreat. Shortly after the jury began deliberating they asked to be reinstructed on the definition of first degree murder, second degree murder and manslaughter. Supplemental instructions were given and the jury resumed deliberations.

The next day the jury asked for additional instructions, namely, (1) the definition of aiding and abetting, (2) whether aiding and abetting can be applicable in second degree murder or manslaughter, and (3) the legal definition of malice. In response the court gave the following supplemental instructions:

* * * the law of this State with respect to aiders and abettors, is as follows:

If two or more persons act in concert in committing a criminal offense such as the one charged here, all who participate in the commission of the offense are equally guilty of this offense regardless of the part each took in the commission of the crime. Consequently, if a killing is brought about by the action of one of those involved, all who are acting in concert are guilty.

So that’s the law with respect to aiding and abetting.

Now, with respect to the — you asked for the definition of malice as I gave it to you. I stated that malice in its legal sense means nothing more than an illegal state of mind. The law presumes that all unlawful homicides, that is, all unlawful killings are committed with malice unless the lack of malice appears from the evidence. That’s the definition of malice.

Now, you asked the third question which is can aiding and abetting be applicable to second degree murder or manslaughter? Aiding and abetting can be applicable to any unlawful act.

Now, I think that answers the three questions, at least, I hope so.

*482Exception was taken to the supplemental charge on aiding and abetting, specifically to the absence of an instruction that intent to aid and abet must be present. Exceptions were also taken by both defendants to the charge on malice, complaining that it was not complete.

.Both defendants contend before us that the supplemental charge on malice was erroneous. Robinson also contends that the earlier instructions placed undue emphasis on the presumption that all unlawful homicides or killings are murder in the second degree unless “rebutted upward by the State by showing * * * that the killing was first degree murder” or “rebutted downward if the evidence shows” that the offense was “no more than manslaughter.” As a result, Robinson contends, the instructions implied that defendants had the burden of proving that the killing, if unlawful, was manslaughter and not murder. Our disposition of the contention regarding the supplemental charge on malice makes it unnecessary to resolve Robinson’s assertion that the burden of “mitigating murder to manslaughter” was impliedly shifted to defendants.1 Reading the charge as a whole (State v. Freeman, 64 N. J. 66, 69 (1973); State v. Wilbely, 63 N. J. 420, 422 (1973)), we conclude, nevertheless, that the supplemental instructions on malice were erroneous and require a reversal of defendants’ convictions.

Murder (N. J. S. A. 2A:113-1 and N. J. S. A. 2A:113-2) is said to be distinguished from manslaughter *483(N. J. S. A. 2A:113-5) by malice, express or implied. State v. Gardner, 51 N. J. 444, 457-459 (1968); State v. Brown, 22 N. J. 405, 410-411 (1956). Manslaughter is an offense distinct from and not a degree of murder, and malice is “the grand criterion which distinguishes murder from other killing.” Id. at 410. At common law all homicides were presumed to be malicious unless the evidence proved otherwise, but murder could be “justified by the command or permission of the law,” or it could be “excused on the account of accident or self-preservation,” or it could be “alleviated into manslaughter * * Id. at 410-411; State v. Gardner, supra.

In his charge proper and in the first supplemental instructions the trial judge stated that all “unlawful homicides or killings are murder in the second degree,” but the presumption of second degree murder is rebuttable upward to first degree or downward to manslaughter, according to the evidence. Defendants contend that in defining malice as “nothing more than an illegal state of mind,” and in charging that all unlawful homicides or killings “are [presumed] committed with malice unless the lack of malice appears from the evidence,” the judge failed to define malice properly and relieved the State of its full burden of proving malice, thus erroneously establishing a presumption in favor of murder over manslaughter.

Earlier cases did say that an “unlawful homicide” is presumed to be murder in the second degree, State v. DiPaolo, 34 N. J. 279, 294 (1961), cert. den. 368 U. S. 880, 82 S. Ct. 130, 7 L. Ed. 2d 80 (1961), and that proof of a “killing” raises a presumption of malice which may be rebutted by the evidence. State v. Williams, 29 N. J. 27, 43-44 (1959); State v. Huff, 14 N. J. 240, 249 (1954). However, these statements are superseded by the ruling in Slate v. Gardner, supra, which makes it clear that the presumption of second degree murder (“any other kind of murder is murder in the second degree.” N. J. S. A. 2A:113-2; emphasis added) applies only as between first degree murder *484and second degree murder; it comes into play for the benefit of a defendant only after the State has proved a murder beyond a reasonable doubt. The presumption of second degree murder plays no role in distinguishing between murder and manslaughter. The prosecution bears the burden of proving malice to establish murder and must disprove facts that would reduce the offense to manslaughter (i.d., 51 N. J. at 459), when the issue is presented by the evidence, just as the prosecution must disprove self-defense when that issue appears. State v. Abbott, 36 N. J. 63, 72-73 (1961); State v. Terry, 41 N. J. 1 (1963); see Mullaney v. Wilbur, 421 U. S. 684, 95 S. Ct. 1881, 44 L. Ed. 2d 508 (1975). The court said in State v. Gardner:

Only when tbe essential elements of murder have been proved beyond a reasonable doubt does the presumption of murder in the second degree arise. This presumption is intended to favor the defendant and to underscore the burden of the State to prove three additional elements, i. e., premeditation, deliberation and willfulness as defined in State v. DiPaolo, 34 N. J. 279, 295 (1961), beyond a reasonable doubt, in order to elevate the crime from second degree to first degree. The presumption has no role whatever in determining whether (1) there was in fact an intent to kill or inflict grave bodily harm (the minimum requirement of murder), or (2) the homicide was. justifiable or excusable, or (3) the homicide was no greater than manslaughter. The State’s burden of proving, beyond a reasonable doubt, that the homicide was murder includes the burden of so proving that the killing was not accidental, justified or excusable, or manslaughter. The State must bear this burden throughout the entire trial and the presumption comes into play only after the State has satisfied this mandate. It must, of course, be remembered in connection with the foregoing discussion that we are not here dealing with a felony murder. [51 N. J. at 459]2

State v. Gardner, supra, 51 N. J. at 459, held that the failure to convey proper instructions on the State’s burden of proof constituted plain error requiring reversal. However, *485the charge in Gardner expressly put the burden on defendant to persuade the jury that the evidence warranted an “alleviation” to manslaughter. The charge in the case at hand did not explicitly shift the burden, but appellants contend that the effect was the same. Stale v. Gardner foreshadowed the recognition of this issue as a matter of federal constitutional import. Mullaney v. Wilbur, supra, recently held that Maine Law violated the due process clause of the Fourteenth Amendment by requiring a defendant charged with murder to establish by a preponderance of evidence that he acted in the heat of passion on sudden provocation in order to reduce the homicide to manslaughter. Due process requires the prosecution to prove beyond a reasonable doubt the absence of facts which make a killing manslaughter when the issue properly appears in the case.

We are satisfied that the judge erred in defining malice in the supplemental instructions. The charge that malice means “nothing more than an illegal state of mind” was erroneous. Coupled with the statement that “[t]he law presumes that all unlawful homicides, that is, all unlawful killings are committed with malice unless the lack of malice appears from the evidence,” the instruction constituted prejudicial error. To say that malice is simply an illegal state of mind blurs the use of the term in distinguishing murder from manslaughter, since both involve illegal states of mind. See State v. Madden, 61 N. J. 377, 386, 395-396 (1972). And to presume malice from any unlawful killing tends to prefer murder over manslaughter, contrary to the principles enunciated in State v. Gardner and Mullaney v. Wilbur, supra.

Of course, malice, being a state of mind, may be inferred from the circumstances of the killing. Mullaney v. Wilbur, supra, 421 U. S. at 692, 95 S. Ct. at 1885, 44 L. Ed. 2d at 516; State v. Brown, supra, 22 N. J. at 410. But there is a vast difference between a permissible inference and a presumption of fact. See State v. DiRienzo, 53 N. J. 360, *486378-382 (1969); Perkins, “A Re-Examination of Malice Aforethought,” 43 Yale L. J. 537, 550 (1934) (hereafter Perkins); cf. State v. DiPaglia, 64 N. J. 288, 294 (1974); Jurman v. Samuel Braen, Inc., 47 N. J. 586, 594-597 (1966). There is no logical basis for presuming that every unlawful killing implies malice. Where the burden is on the State to prove every fact necessary to constitute the crime (Mullaney v. Wilbur, supra; In re Winship, 397 U. S. 358, 364, 90 S. Ct. 1068, 1071, 25 L. Ed. 2d 368, 375 (1970)), instructing a jury in terms of presumptions of fact rather than permissible inferences presents risks of constitutional dimension. See State v. DiRienzo, supra; see also Barnes v. United States, 412 U. S. 837, 93 S. Ct. 2357, 37 L. Ed. 2d 380 (1973); Leary v. United States, 395 U. S. 6, 89 S. Ct. 1532, 23 L. Ed. 2d 57 (1969); United States v. Romano, 382 U. S. 136, 86 S. Ct. 274, 15 L. Ed. 2d 210 (1965); Tot v. United States, 319 U. S. 463, 63 S. Ct. 1241, 87 L. Ed. 1519 (1943).

The problem may be clarified further by considering the definition of malice — a matter of some controversy. See State v. Gardner, supra, 51 N. J. at 458; Perkins, supra. Its usefulness as a word of art to convey the distinction between murder and manslaughter must be questioned. Cf. State v. Madden, supra, 61 N. J. at 396-397.

Malice has been variously defined. In some contexts it is described as merely the intentional doing of an unlawful act without justification or excuse, regardless of consciousness of wrongdoing. Morss v. Forbes, 24 N. J. 341, 358-359 (1957); see also id. at 379-380 (Weintraub, J., dissenting). Often used synonymously with criminal intent as knowing wrongdoing, the “concurrence of an "evil meaning mind with an evil doing hand,’” (State v. Fair, 45 N. J. 77, 90 (1965); State v. Williams, 29 N. J. 27, 41 (1959); Morisette v. United States, 342 U. S. 246, 251, 72 S. Ct. 246, 249, 96 L. Ed. 288, 294 (1952)), the term is also given more invidious characteristics such as an “evil de*487sign in general, the dictate of a wicked, depraved and malignant heart” (State v. Brown, supra, 22 N. J. at 410), possibly even animated by anger or hatred (see State v. Huff, supra, 14 N. J. at 249). But proving a hateful motive is not essential to proof of malice, for, as noted, historically malice was presumed from the intentional commission of the wrongful act. Id.; Perkins, supra at 548-551. The real difficulty is that the meaning of malice in common understanding and usage, as well as in law, is not suitably exact for defining crimes as serious as murder and manslaughter. In fact, the term “malice aforethought” which had various particular meanings in the law of homicide (see Perkins, supra at 544 — 551) has given way to mere “malice” with all its loose connotations.

A knowing intention to do an unlawful act constitutes mens rea, criminal intent — an “evil intention.” State v. Labato, 7 N. J. 137, 149 (1951). One can intend less than serious bodily injury and still act with an evil-meaning mind. This was illustrated in State v. Madden, supra, where a police officer was attacked and killed by a mob composed of persons who may have had diverse criminal, evil intents, ranging from an intent to kill, to injure, to interfere with the officer’s performance of his duty or merely to harass or humiliate. 61 N. J. at 396. However, the court said that if death resulted from an act not performed with the intention to do some injury to the officer, the crime would be involuntary manslaughter, not murder. Id. at 386. Thus, unlawful acts causing death which are performed with evil intention or hatred may constitute murder or manslaughter — or possibly only a gmsi-criminal offense.

State v. Madden highlights the need to deal in specifics when charging a jury. It proves the inutility of the phrases “an unlawful act,” “criminal intent” or “an evil meaning mind” when defining degrees of homicide. Id. at 395-397. The need to deal in specifics is no less acute because the term malice has an ancient history as the sign of murder.

*488Thus, when distinguishing murder from manslaughter it is desirable to define murder as a killing committed (a) with the intent to kill or to do grievous bodily harm to any person or (b) with knowledge of the likelihood of death or grievous bodily injury accompanied by an indifference to the result. State v. Gardner, supra, 61 N. J. at 458; State v. Madden, supra, 61 N. J. at 385. Involuntary manslaughter is distinguished by an intent to inflict less than serious injury, id.; and it includes an unintentional killing such as results from the reckless handling of a firearm. See State v. Bonano, 59 N. J. 515, 523 (1971). Voluntary manslaughter is a killing committed in a sudden transport of passion induced by provocation sufficient to inflame an ordinal, reasonable person. State v. Madden, supra, 61 N. J. at 399-400; State v. Guido, 40 N. J. 191, 209 (1963); State v. King, 37 N. J. 285, 299-301 (1962). These definitions are not complete, but they illustrate a proper focus upon essential elements of the crimes without the distortion engendered by concepts of evil.3 To say that malice can be inferred from circumstances which prove an intention corresponding to the conditions of murder is tautological at the very least. Nothing is lost by omitting the term “malice” in instructing a jury,4 and State v. Gardner and State v. Madden strongly suggest the need to emphasize specific acts and intents in differentiating murder from manslaughter.

*489As we have said, the brief definition of malice in response to the jury’s inquiry was inaccurate and misleading. We cannot say that the error was made harmless by earlier instructions which properly defined manslaughter and the State’s burden of proof. Since we must reverse on this point no purpose would be served by reviewing in detail the supplemental charge on aiding and abetting or considering its potential for prejudice. The instruction was obviously incomplete. It did not embrace the statutory definition — to aid, abet, counsel, command, induce or procure, N. J. S. A. 2A:85 — 14 — although the phrase “act in concert” did suggest community of purpose. See State v. Sullivan, 43 N. J. 209, 236-237 (1964), cert. den. 382 U. S. 990, 86 S. Ct. 564, 15 L. Ed. 2d 477 (1966). But the possibility that separate participation and intent will establish different kinds or degrees of crime, or none at all, committed by each defendant (State v. Fair, supra, 45 N. J. at 94-96) made it essential to discuss intent as part of the aiding and abetting charge. As stated in State v. Madden, supra:

* * * if two should attack and one of them intends only a simple assault and battery and is unaware of the intent of the other to use deadly force, he would be culpable only according to his own intent and wrong. But if he participates in an attack or continues in it with an awareness of the purpose of others to kill or to do grievous bodily harm, he is chargeable with that further intent and result. [61 N. J. at 391]

We need not deal with the plain error contention concerning the omission to charge the effect of mere presence at the scene. See State v. Madden, supra, 61 N. J. at 397-398; State v. Fair, supra, 45 N. J. at 95.

The convictions of defendants are reversed. The case is remanded for a new trial.
