Evil is definitely blind, driven by ignorance ... but it's still kind of relative. I mean, we don't actually know everything in the Universe. Were we not humans, what would we care about a genocide in Rwanda? If some advanced alien species were to observe us, would they look at us as evil, or simply as a lower life form? Wild dogs will tear the hell out of one another, and the pack will often turn on the weakest member. Is it really evil? Or is it just nature? Are we really all that, or are we just organisms in one of the Universe's great petri dishes?
