so you'd just have people who were really bad at being good. =) There was no real evil for them to fight for. Thus, at worst, they were excessively selfish.
Still, since that sounds far too simplistic:
Demmy was a writer and big man in society until he fought to destroy the world. He was LTT's backup in case he bought it. Same with Belal, I think.
Semi was the best healer living, even if she took her sadistic pleasures later. She's right, btw - if the only person who could keep me alive hurt me afterwards, I'd call it square.
Graendal preached asceticism and healed mental illness. Then one day she came back as a gluttonous nut-bar. I always hoped there would be a juicy story behind that...
Sammael was basically the pre-affair Tiger Woods/Shaq/Babe Ruth of his time.

I described them more directly as pillars of the community, not as good-natured. Looking at important folks in society, you can add Ishy, Asmodean, and Lanfear. Remember that having a 3rd name meant great accomplishment, and their world rewarded best those who helped society most. So anyone with a 3rd name must've done a lot of good in the world, even if they were ultimately selfish. The start of the AoL shook the public up because well-respected folks suddenly proclaimed for Shaitan. And I think Aginor & Balthamel had 3rd names also, so they might qualify as well.
