"His own inconsistency was one of the sources of his torment."

In the aftermath of this event, the patient exhibited not only classic post-traumatic symptoms but also evidence of pathological grief, disrupted relationships, and chronic depression: “He had, in fact, a profound reaction to violence of any kind and could not see others being injured, hurt, or threatened. . . . [However] he claimed that he felt like suddenly striking people and that he had become very pugnacious toward his family. He remarked, ‘I wish I were dead; I make everybody around me suffer.’”
The contradictory nature of this man’s relationships is common to traumatized people. Because of their difficulty in modulating intense anger, survivors oscillate between uncontrolled expressions of rage and intolerance of aggression in any form. Thus, on the one hand, this man felt compassionate and protective toward others and could not stand the thought of anyone being harmed, while on the other hand, he was explosively angry and irritable toward his family. His own inconsistency was one of the sources of his torment.

Authoritarian, secretive, sometimes grandiose, and even paranoid, the perpetrator is nevertheless exquisitely sensitive to the realities of power and to social norms. Only rarely does he get into difficulties with the law; rather, he seeks out situations where his tyrannical behavior will be tolerated, condoned, or admired. His demeanor provides an excellent camouflage, for few people believe that extraordinary crimes can be committed by men of such conventional appearance.
