It all boils down to the fact that no matter what, evil people are th most noticed. If your a nice guy, people play you for th chump, but if your a blood sucking beast from the dark recesses of Hell, people are going to notice you, be afraid of you, and not do anything stupid to you. Th aura idea seems good to me, but how much time would you have to do anything if he were bad? Walks up and kills you for no reason, evil people do that stuff, happens to me all the time in Ultima Online. Instead of text, maybe this dark fog could hover around that character, but if your good you glow white or something?
