Sin, young man, is when you treat people like things. Including yourself. That's what sin is. It's a lot more complicated than that-- No. It ain't. When people say things are a lot more complicated than that, they means they're getting worried that they won't like the truth. People as things, that's where it starts. Oh, I'm sure there are worse crimes-- But they starts with thinking about people as things... --from Carpe Jugulum, by Terry Pratchett.
