“The first reaction of the legal profession to the irresistible impulse defense, when it was introduced to the law many years ago, was inclined to be favorable. Then a change set in and for many years the prevailing view was strongly against its recognition. Present indications are that the tide is changing again. There seems to be a growing belief to the effect that ignoring the possibility of such a defense fails to give full recognition to the fundamental concept of mens rea.” Rollin M. Perkins & Ronald N. Boyce, Criminal Law 975 (3d ed. 1982).
