"The psychopath is a rebel, a religious disobeyer of prevailing codes and standards... a rebel without a cause, an agitator without a slogan, a revolutionary without a program; in other words, his rebelliousness is aimed to achieve goals satisfactory to him alone; he is incapable of exertions for the sake of others. All his efforts, under no matter what guise, represent investments designed to satisfy his immediate wishes and desires."
