And about being evil in the game, there are many quests with a evil route and a good route, such as the LOCH. It was a long time ago, but I remember having A Zhi in my party (Need to be very evil). And I remember this one time, where I was fighting the end game battle, and I died during the first (or was it second?) round of combat.
