What a mountain from a molehill!

Right, back we go to the tribal past. The Tribe has a set of Rules. If you follow the rules, you are Good, if you break them you are Evil and we kil you or throw you out to starve. That's Evil Type One - Breaking Our Rules is Evil

There are other Tribes out there who have different rules. They are a threat to us and therefore Evil. Thus Evil Type Two - what we do is Good, what they do is Evil. Even when we do the same things they do, we do it in a Good way, they do it in an Evil way.

Evil is not, and has never been, a problem. The problems are our people not obeying rules and other people not being us.

Everything else is fluff.
