Me either. Sure it sounds like fun to be able to KILL ALL; TAKE STUFF with no conscience or concern for anybody else (except the rest of the group) - for a while. There is no overall goal or purpose to it. If you are successful enough, you become the target of meddling powerful Heroes who want you dead. Or worse - they want to torment you for the rest of your natural life, trying to persuade you to repent and convert into something against your essential nature: another hero!![]()

There are gray areas, but mostly is good vs evil. (Archetypical ones)
