"For thirty years you dreamt you were a hero, and condoned a thousand petty lapses--because a hero, of course, can do no wrong."
-- Sartre

When you feel that you have an enemy, or that you're on the right side of an issue, that becomes a justification in itself. You're not as bad as THEM. Being on the right side has bought you those thousand petty lapses.
