As a player who, at the lightest, is either natural or evil -although I have played through every option- I found him intolerable and never used him unless forced to, something the aforementioned tweak permanently fixed. Why cannot we kill off these annoying characters - oh, that's right, no one would want to have them in the party if we had that option. At least Carth ran off, and was killed if you used that restoration, although it happened about a full game too late for my tastes. Well, I guess convincing his son to be a sith was a plus that would have been missed...
