We generally describe the most repulsive examples of man's cruelty as brutal or bestial, implying that such behavior is characteristic of less highly developed animals than ourselves. In fact, however, the extremes of brutal behavior are confined to us: there exists no parallel in nature to our savage treatment of each other. The unmistakable truth is that man is the most vicious and cruel species that ever walked the earth.
