Opinion op the court by
JUDGE O’REARReversing.
Appellant was convicted of the charge of murder, committed upon Eiley Webb. The defense was emotional insanity, and justifiable homicide under an apparent necessity. Appellant and liis wife bad become estranged and had temporarily separated about two years before the killing- of Webb. Appellant claims that the separation ivas because of Webb’s interference with the domestic relations of appellant and his wife. Just before the killing, appellant and his wife had agreed to be reconciled and to resume tlie married relation. *934For that purpose, appellant visited her at her father’s home in Letcher county. Past offenses were condoned, and appellant started to his home, in Leslie county, to prepare for taking his wife there some days later. He was turned back, however, and returning somewhat unexpectedly, found his wife and Webb in company, from which it was reasonably apparent, and proved io he a fact, that they had again been guilty of adultery. The next morning appellant was talking to his wife at her father’s, when Webb came to the house, Appellant claims that his wife told him that Webb had threatened his life, rather than that she should leave with him. Incensed at the continued provocation, as he claims, appellant picked up a rifle and shot Webb fatally. He also claims that, at the moment of the shooting, Webb turned upon him with something in his hand, which appellant thought was a pistol. The verdict of the jury found appellant guilty, and sentenced him to life imprisonment.
Upon the trial there occurred a number of errors for which the judgment must be reversed.
In the first place, it was error for the trial court to have admitted evidence to the jury that appellant had committed other crimes, or that he had been guilty possibly of adulterous acts himself; that he had shot another man, or that he had said that Webb was the third man he had shot. The fact that appellant had shot Webb was-not in dispute. His admission of the fact that he had shot him, and that he was the third man that he had shot, could serve no useful or proper purpose in the trial, as it was testified to; appellant having said merely, according to Commonwealth evidence, ‘-He is the third one I have knocked down.” Its tendency was rather to lead the minds of the jury away from the consideration of the main facts before them, and tended to prejudice appellant’s cause in their minds. For it might be ar*935gued, not unreasonably, that if appellant had shot two men before, and was boasting of it, he was a bad man, and one very likely to have committed a. crime of a similar nature in this case. In fixing his punishment, the jury were apt, too, to regulate it somewhat by his previous offenses, whereas the only matter legitimately before the jury was whether appellant had feloniously killed Webb, and, if he had, the proper measure of punishment for that act.
Appellant offered to testify that his wife told him immediately before the shooting'that Webb had threatened his life, and would kill him rather than let her return with him. The court excluded this evidence upon the ground, it is said, that it was in the nature of a confidential communication between husband and wife, and, as such, was incompetent as evidence, under the Oode. In Arnett v. Commonwealth, 114 Ky., 593, 24 Ky. Law Rep., 1440, 71 S. W., 635, it was held that a dying statement made to the wife of the declarant could be proved against his slayer; that section 606, Civ. Code, “that the wife was incompetent to testify even after the cessation of the marriage relation, to any communication made to her by her husband during marriage,” did not apply to criminal prosecutions. With respect to these the common law is in effect in this State, of which Greenleaf on Evidence, section 337, says: “The great object of the rule is to secure domestic happiness by placing the protecting seal of the law upon all confidential communications between husband and wife, and whatever has come to the knowledge of either by the means of the hallowed; confidences which that relation inspires can not be afterwards divulged in testimony, even though the other be no longer living.” The rule is1 •founded upon the policy of the law, the object of which is to secure domestic happiness by protecting that state in the inviolability of its confidences. What would tend to create *936a breach of such confidences is therefore disfavored by the law. But under the circumstances shown in the case at bar, the liberty or life of one accused with a high crime is involved. The main ingredient of his act, aside from the death inflicted by it, is its motive. If the act were inexcusable — done in cold blood, as- the saying is, and therefore in malice — the perpetrator became a criminal, subject, under the law, to capital punishment. On the other hand, if the act was excusable, he has, in law, done no wrong, or, if the act was done under such provocation, as to inflame- passion beyond control, under the circumstances, the offense is greatly reduced. Instead of being a capital one, it might he punished by a short confinement in the State penitentiary. The State is concerned in eliciting the truth with respect to homicides committed within her borders, and in no sense is it'the purpose of'the State to convict for a higher degree- of crime than is really justifiable by the facts of the case. No other policy of the law can override the State’s desire to do justice, and no more, to fhose charged in her courts with ■('■rime. If the fact he that the deceased, Webb, had violated the sanctity of appellant’s home, had estranged his wife’s affections, liad debauched her person, and had threatened appellant’s life if he proposed, to interfere wifli deceased’s continuance of his illicit relations, forcing his presence upon them for that apparent purpose, human nature is so constituted that the passion of the husband may well be supposed to have been aroused to an uncontrollable extent. Whether it was such as to have created an emotional insanity, so as for 1he time to dethrone the reason of the outraged husband, or whether it merely reduced the homicide to manslaughter, was a question which, under the circumstances, ■should have been submitted to the jury. It was not enough, though, to have instructed them appropriately as io the law" *937ordinarily applicable to murder and manslaughter/ They •should have been allowed to consider in connection with the instructions the facts which probably entered into shaping the conduct of the accused on the fatal occasion. If the facts should be, as appellant claims, that his wife had. been debauched by the person whom he afterwards slew, and that the debauchee was flaunting his successes in the face of the victimized husband, it would assuredly be competent to prove the fact before the jury, at least in mitigation of the husband’s act in taking his life cn the spot. The sole question here is whether the husband might show that he got his information from his wife. That he did so get it, for the purposes of this discussion, will be assumed. Having it, it' is for the jury to say to what extent, if at all, it palliated his act. But as shown in this record, that fact could not be brought to the knowledge of the jury, except defendant proved or some one else proved that defendant had got such information. That he got it.from his wife could take nothing from the sting of it. Its effect upon his mind and conduct must have been at least the same as, if not, indeed, worse than, if it had been communicated by some third person. If one is informed by his wife that she had been raped, or that a rape had been attempted upon her person, or that ■she had been grossly insulted and assaulted, pointing out the perpetrator of the act at the time, it would not be unnatural for the husband to act upon that information. To allow it to be proved that he acted drastically, without being permitted to show why, or upon what basis his belief rested, would be applying the rule for the protection of domestic felicity so as to make it hurt instead of help those for Avhose benefit it was primarily intended. We perceive no good reason for extending the rule invoked so as to exclude the evidence discussed. The court is of opinion *938that the evidence should have been admitted, to be weighed by the jury as other facts and circumstances in the case.
Appellant filed an affidavit to procure a continuance on account of the absence of certain witnesses. The Commonwealth consented that the affidavit should be read, under provisions of the Code, as the depositions of the absent witnesses, whereupon appellant’s motion for a continuance was ■overruled, and ihe affidavit was so admitted. In the concluding argument to the jury, the Commonwealth’s attorney said, in evident response to the argument made on behalf of appellant, that the supposed testimony of these absent witnesses was not in fact their sworn testimony, but was merely an affidavit filed on behalf of the defendant. From which it was argued, or at least the inference was necessarily invited, that the testimony of the absent witnesses was not in fact, nor was it to be received by the: jury as, their evidence in the case. This was an abuse of privilege by the commomvealth’s attorney, and objections of appellant should haye been sustain to the argument, and the jury admonished appropriately. The law gives to the defendant in such case the benefit of such statements as the depositions of the absent witnesses. That is the least that he is entitled to, under the guaranty of of the Constitution,, and the law affording one charged with crime compulsory process to procure the attendance of witnesses on his behalf at his trial. If the practice should be indulged by the prosecution of discrediting the affidavit by informing the jury that it was not in fact the deposition of the witness, it would be to nullify the provisions of the statute, and to deprive the defendant of a valuable privilege, which the Legislature, in its wisdom, has deemed a necessary one in the proper administration of justice. In condemning a similar remark (Redmond v Commonwealth, 51 S. W., 565, 21 *939Ky. Law Rep., 331), tliis court said: “The defendant was entitled to the full benefit of the statements therein as coming from Purcell [the absent witness]. This same practice is indulged in to some extent throughout the State, but should not he permitted by the court.”
The other evidence complained of, we think, was admissible. But for the reasons indicated, the ease must be 'remanded for a new trial, under proceedings not inconsistent with this opinion.
