People who demonstrate evil see the world as they want to see it rather than how it actually is. To maintain their version of reality, they must scapegoat others and project their own faults onto them. They must attack any and all who jeopardize their self image. All of this means that those who demonstrate evil are entirely incapable of true empathy and can be utterly destructive in their relationship with others in the name of self-preservation.
— Christie Koehler (summarising part of the message of People of the Lie, by M. Scott Peck)
