The important thing is moral choice. Evil has to exist along with good, in order that moral choice may operate. Life is sustained by the grinding opposition of moral entities.
Anthony BurgessIf you expect the worst from a person, you can't ever be disappointed... The pessimist takes a sort of gloomy pleasure in observing the depths to which human behaviour can sink. The more sin he sees, the more his belief in Original Sin is confirmed. Everyone likes to have his deepest convictions confirmed; that is one of the most abiding of human satisfaction.
Anthony Burgess
