Tzvetan Todorov quotes:

People who believe themselves to be the incarnation of good have a distorted view of the world.

We should not be simply fighting evil in the name of good, but struggling against the certainties of people who claim always to know where good and evil are to be found.

For evil to take place, the acts of a few people are not sufficient; the great majority also has to remain indifferent. That is something of which we are all quite capable.
