Violence is the preeminent evil of our day. Though the causes of destructive violence in our society are complex, the troublesome human emotions of anger and rage play a central role in the genesis of violent behavior and psychopathology in general. In this paper, the author discusses forensic evaluation and psychotherapeutic treatment via “existential depth psychology”—a synthesis of Freudian, Jungian, and existential theory—focusing on the overlooked links between repressed anger or rage, pathological narcissism, antisocial personality, and violent behavior.
