I have never seen or heard of evil - ya' know, some mystical force like the Dark Side, right? Only from Hollywood, politicians, and/or religious people, have I heard of such a thing.I do not believe in evil. Do you?
In the real world there is stupid and there is crazy. Those are the bad elements in any society. They overlap, too. They manifest in all sorts of ways, but in the end, it is some combination or one of the two that are at the heart of all malice.
I could write for a million hours on the subject, and I'm no psychiatrist, or theologian, but suffice to say, if you believe there is evil in the world, you may be stupid enough to suffer it. Be careful what you believe in. You can undo stupid. Crazy is a harder thing to beat.
