The perfectly decent person who follows a certain chain of reasoning, ever so slightly and subtly incorrect, becomes a perfect monster at the end of the chain.
-Wallace Shawn-

People who claim they’re evil are usually no worse than the rest of us. It’s people who claim that they’re good, or any way better than the rest of us, that you have to be wary of.
-Gregory Maguire-

A man’s subconscious self is not the ideal companion. It lurks for the greater part of his life in some dark den of its own, hidden away, and emerges only to taunt and deride and increase the misery of a miserable hour.
