Theology is pretty interesting.

This may be a bit too off topic [s]pleasenobullyGMtan[/s] but what line of thought led you to that conclusion?

I don't want to go into the whole long thing, but the Cliffs Notes version is that since this world has (according to the Bible) been fallen since the Garden of Eden, everyone is born with a fallen nature.  If you look at Eden as a triumph of human nature over some sort of divine plan and add that to a lot of what's happened in human history, it makes sense to see human nature as innately self-serving.  Since I came to the conclusion that any given human will always act in their interest first, I feel justified in expecting people to screw others over as soon as it helps them.  Kinda emo 13-year-old, I know.
