" The myth of pure evil depicts innocent victims fighting against gratuitously wicked, sadistic enemies. The myth encourages people to believe that they are good and will remain good no matter what, even if they perpetrate severe harm on their opponents. Thus, the myth of pure evil confers a kind of moral immunity on people who believe in it. As we will soon see, belief in the myth is itself one recipe for evil, because it allows people to justify violent and oppressive actions. It allows evil to masquerade as good. "
