Hatred, which could destroy so much, never failed to destroy the man who hated, and this was an immutable law.
“Now if you’re a human being, you probably realize that it’s possible for you to degenerate into a beast; people who don’t acknowledge this have actually degenerated in a different way, have lost a certain amount of self insight. And you can regress into being an ape, if that’s what you really want to do.”
Gene Wolfe
