" malefactor becomes the creature of his own deeds. Once the transition has been overpassed a new set of standards comes into force. The perceptive malefactor recognizes his evil and knows full well the meaning of his acts. In order to quiet his qualms he retreats into a state of solipsism, and commits flagrant evil from sheer hysteria, and for his victims it appears as if the world has gone mad. "
