“In my work with the defendants, I was searching for the nature of evil and I now think I have come close to defining it. A lack of empathy. It’s the one characteristic that connects all the defendants, a genuine incapacity to feel with their fellow men.

Evil, I think, is the absence of empathy.”

- Captain G. M. Gilbert, U.S. Army Psychologist assigned to
watch the defendants at the Nuremberg trials (1945-1949)
