"The particular direction in which this obliteration may manifest itself depends largely on the temperament of the individual and the circumstances of the case. In some men it results in paralysis of the energies, changing the character into shiftlessness. In other cases it results in destroying the moral sense, but does not amount to positive viciousness, while on the other hand it may result as it unquestionably did in this case, in absolutely perverting the affections so as to render the man incapable of the natural feelings of a husband and father, and supplying motives which seem to be of the most inhuman character. They are inhuman and unnatural, but in such cases it is not correct to hold the man as responsible for the deplorable results unless it is clearly proved that the mental unbalance was brought about by his own acts, performed in a state of conscious free will. The law clearly recognizes that the drunken man is insane, and holds him responsible for his acts committed while drunk, if he became drunk through his own volition. If the liquor is proved to have been forced down his throat or he has been drugged by some one else and his mental balance dethroned thereby, he is not responsible. "It is a very nice question to decide in this Hawes case whether the depraved condition alluded to was the result of his own acts or of his domestic troubles. There is no doubt in my mind but that the species of insanity referred to, existed in the mind of Hawes at the time of the tragedy. "It is a principle in medical jurisprudence that the more atrocious the crime the stronger is the presumption of insanity in the perpetrator. It is a fact wholly creditable to human nature that horrible crimes are rarely, if ever, committed by persons in a normal state of existence. The popular mind is not prepared to receive evidence of insanity in such cases because of the revengeful feeling which naturally animates the minds of men under such circumstances. And there is another difficulty in the way of justice in the fact that this form of insanity is rarely accompanied by such evidences of mania as the uninstructed would demand as necessary to constitute insanity. The perverted state of the affections and the judgment are not necessarily accompanied by the wild ravings and glassy eyes of the lunatic. Emotional insanity of this type is only temporary. It may, also, only affect a few faculties of the mind necessary to the perpetration of the deed, while the mental balance of nine-tenths of the man may remain undisturbed.
