This case comes up on points reserved for our consideration, by the presiding judge of the Jackson Circuit court, before whom the prisoner was tried, for the murder of Tandy W. Lewis, and convicted.

The points reserved will better appear by a- reference to the following statement, signed and sealed by the judge, as a bill of exceptions:

*310- “ Be it remembered, tu at in the trial of this canse, Jabez, Perkins was offor’ed as a juror, and having-been first sworn to answer questions, &c. the question was propounded to this effect, ‘have you formed and expressed an opinion' as to the guilt‘or innocence of the prisoner at the bar?’ Said Perkins replied, that he had so formed and expressed an opinion. To the question whether he formed and expressed said opinion, on hearing the evidence in relation to said charge, or upon his own knowledge of the facts, or upon rumor? said Perkins answered, that he had so formed and expressed said opinion, on hearing the facts stated, by a man in whose veracity he had implicit confidence; which man said be had received his information from one of the witnesses : thereupon the defendant, by his counsel, objected to the competency of said juror, and challenged him for cause; but the court overruled said objection, and determined said juror to be competent, and required said defendant to accept said juror, or challenge, said juror peremptorily, or for other cause; upon which the prisoner challenged said juror peremptorily, at the sametime demanding, that said point should be reserv-' ed; and the number of challenges allowed by law, were exhausted, before said jury was complete, and the said defendant compelled to accept two jurors, without the right of peremptory'challenge. But the said number of peremptory challenges was not exhausted at the tinje said Perkins was determined, by the court, to be competent.

“And in the further progress of said cause, said defendant offered evidence to prove the general character of said Tandy W. Lewis, deceased, with whose murder the defendant is charged; for acts of general *311violence and outrage. There having been no proof, or allegation, of acts of violence or outrage, or 'threats, by said Lewis, towards said prisoner, previous to the occasion of his death ; which evidence having been objected to by the solicitor, Charles Lewis, Esq., the court sustained the objection and excluded the evidence. To which last opinion of the court, the defendant also excepted.” - . ,

Two points were reserved for the opinion of this court, as novel and difficult:

First — Whether the juror, Perkins, was compe-fent? and

Second — Whether the testimony Was properly rejected!

Before we say any thing about the common law 'right of challenging a juror, on what was considered a good ground for challenge, it will be proper, perhaps, to inquire what is the.true construction of our act of assembly, !! the more effectually to secure tfL als in capital cases by impartial jurors;” as this act, in all probability, influenced the presiding judge, on the first point reserved : and, for the purpose of more easy reference, we will here recite so much of the statute as 'can be, in any way, material to be considered :

“ Be it enacted, that, in the selection of a jury, for the trial of a person charged with the commission of a capital crime, it shall be the duty of the court* after the juror is sworn, to make true answer to such questions as may be damanded of'him, by the court,to ask the juror, if he has formed and expressed an opinion, as to the guilt or innocence of the prisoner at the bar. If the juror answers that he has formed and expressed an opinion, then the court shall de-*312inand of him whether the opinion he has so formed and expressed, is formed'upon his own knowledge of the facts, or upon rumor. If he answer that the opinion so formed and expressed, is formed upon his own knowledge of the facts, then he phall be rejected; but if he answer that his opinion, so formed and expressed is formed upon rumor, then he shall be sworn in chief, unless .challenged by the prisoner, or prosecuting officer.”

Whatever may have been the object of this act of our assembly, it seems to me that it can, in no way, operate on more than two grounds of a formed and expressed opinion. The'first is, where it is from the juror’s own knowledge, and this is sufficient to disqualify him from serving as a juror. The second is, where it is derived from rumor. If there is a foundation less, certain than the juror’s own personal knowledge, but more certain, and more to be relied on than mere rumor., it would be an intermediate ground, not embraced by the act of assembly. We can not believe that the legislature intended that these two classes, opinions formed on personal knowledge, and opinions formed on rumor, should cover the whole ground of challenge, on the ground of a preconceived and expressed opinion. It could not have been intended, that an opinion formed' on facts, not personally known to the juror, but so well authenticated, that in the ordinary transactions of mankind, would govern their minds on the subject, should be embraced by the term, rumor. To use the term rumor in such a sense, would be giving form and substance to a shadow, and. would be assuming an interpretation never claimed for it by the most approved Lexicographers and standard writers in our language^ It *313would be no longer a “ pipe blown by surmises, jealousies, conjectures;” it would flow in a more palpable and tangible stream. Mr. Webster, in his valuable Dictionary, defines rumor to be “ a flying or popular report, a current story, passing'from one to another, without any known authority for the truth of it.” If this is the true definition of rumor, there must be many grades between it and the truth, from a personal knowledge of the facts. And it would seem, that a true construction of our statute would not embrace those intermediate grades; and their sufficiency, as a> ground of challenge, would remain to be tested by the principles and practice of< the common law. In taking leave of the act of the legislature, supposed to have influenced the decision of the presiding judge, in the court below, I will further remark,-that it does not seem-to me to have made the slightest innovation on the common law practice, as adopted by this court, in the case of The State vs. Coleman Williams, decided prior to the enactment of the law. The grounds declared by the statute, to be insufficient for a challenge, for cause, were ruled, in that case, to be insufficient, and the same ground ruled to be a good ground for challenge — is so ordained by the act of the legislature. The enactment could only satisfy the doubts of some who were not satisfied with the opinion of the court.; and this is the only beneficial influence that, can result from it.

We will now inquire,- whether the foundation, on which Perkins had formed and expressed an opinion, was based on any thing less certain than personal knowledge, and yet more certain than rumor.— In his answer to the interrogatory propounded, he says, that he derived his information from “ a man, *314in whose veracity he had implicit confidence, who said that he had received his information from one of the witnesses.” The channel through which the information came to the juror, is here given, and is much more certain than the definition before given, of the idle, vagrant ramors. But.it was not ascertain as his personal knowledge would have been. The source of the information is, therefore, intermediate; and it will only .remain for us, on this point, to inquire, if it constituted a sufficient ground of challenge. The doctrine on this subject is fully discussed, and the rule clearly laid down in the opinion of this court, in the case of The State vs. Coleman Williams. In that case, the rule said to have been declared by Judge Spencer, on the trial of Yan Alston, for the murder of Huddleston, is fully recognised : “ That, if a person had formed or expressed an opinion, for or against the prisoner, on a 'knowledge of any of the facts attending the murder, or from information of those acquainted with the facts, he considered it good cause of challenge.”

In this case, although the juror, Perkins, professed to have no personal knowledge of Ihe facts, his opinion was founded, upon what he considered, an authentic source, and the impression was as strong as'if he had heard it himself, from the witness. Not a link is wanting in the chain of communication, from the witness to the juror: it was told by the witness to a person in whose veracity, confidence was reposed, who communicated it to the juror. This seems to me, to be a case within the rule laid down by Judge Spencer, and reeognised by this court.

I have not referred to authorities, because the question underwent so full an investigation in this *315court, in the case referred to, that to repeat the conclusions drawn from authorities, then exarninined, would be an unnecessary labor, that could shed no new light upon the subject.

The second point reserved for the opinion of this court, is, on the admissibility of the testimony offered by the prisoner, and rejected by the court.

The circumstances, under which this testimony was offered, aro not shown, by the record, with sufficient clearness, and distinctness, to enable this court to determine, whether' it ought to have been admitted, or not. That the good or bad character of the deceased, as an abstract proposition, can haye no influence on the guilt of the accused, is too clear to admit of controversy. ' To murder the vilest and most profligate of the human race, is as much a crime, as if he had been the best, the most virtuous, and the greatest benefactor of mankind. ' But, there can be no doubt, but that, when the killing has been under such circumstances, as to create a doubt as to the character of the offence committed, that the general character of the accused/may sometimes afford a clue, by which the devious ways, by which human action is influenced, may be threaded, and the truth attained. It is an acknowledged principle, that, if, at the time the deadly blow was inflicted, the person who so inflicts, has well founded reasons to believe himself in imminent peril, without having, by his fault, produced the exigency, that such killing will not be murder.

If the deceased was known to be quick, and deadly, in his revenge of imagined insults — that he was ready to raise a deadly weapon, on every slight provocation; or, in the language of the counsel, his *316“garments were stained with .many murders”— when the slayor had been menaced, by such an one, he would find some excuse, in one of the strongest impulses of our nature, in anticipating the purposes of his antagonist. The language of the law, in such a case, would be, obey that impulse, to self-preservation, even at the hazard of the life of your adversary.

.If the killing took place, under circumstances, that could afford the slayor no reasonable grounds, to believe himself in peril, he could derive no advantage, from the general character of the deceased, for turbulence and revenge. But, if the circumstances of the killing were such, as to leave any doubt whether he had not been more actuated by the principle of self-preservation, than that of malice, it would be proper, to admit any testimony, calculated to illus-rate to the jury, the motive by which he had been actuated.

To this course, we can see no good objection ; and, it seems pretty certain, that it would oflon shelter the innocent from the influence of that sound, but not unfrequently severe, maxim of law, that, when the killing has been proven, malice jwill be presumed, unless explained and rebutted. There can be but little danger of .the guilty escaping, under the influence of a prejudice, created by such testimony, against the deceased. The discretion of the judge will .be able to. control and prevent such-a result.— And jurors will be able to comprehend the reason and object of such testimony.

As I before remarked, it does not appear, from the record, with sufficient clearness, under ,what circumstances, this testimony was rejected, to authorise us *317to say, tliat it was improperly rejected. We do riot know, that the views we have expressed, were departed from, and we would hesilate, to reverse the judgment on this ground. But, the judgment must be reversed ou the first point, reserved for our consideration ; and remanded for a new trial. — And this is the opinion of the court.
