M.S. Peck on evil

Evil is not committed by people who feel uncertain about their righteousness, who question their own motives, who worry about betraying themselves. The evil in this world is committed by the spiritual fat cats, by the Pharisees of our own day, the self-righteous who think they are without sin because they are unwilling to suffer the discomfort of significant self-examination.

~ M.S. Peck, People of the Lie: the Hope for Healing Human Evil (1990)
