'Bout Quallos "friend"
Well, last time I was there I was playing a CG sorcerer with high INT and WIS.
Quallos speech made it pretty clear to me (NOT my char) that he was under some kind of domination. For a smart sorcerer it would have been even easier.
As they were under domination, they weren't really friends. They were just told to act like they were. No more evil than killing a wild carrion crawler.
On a purely roleplaying standpoint, your character does not see those colored rings which tell you if something is hostile. Most adventures would (probably) have assumed that a carrion crawler was attacking some poor man in his home.
