Well, tis a nice thread. Reasons to think Minsc is evil:
He regects you if you have a low charisma, and he's really harsh doing this.
I dislike his battle shouts. Xan, and even Branwen seem better to me.
I used to overtime his quest because I wanted to pick up and sell every and all item to a merchant downtonw, and he would attack me often, for no XP at all.
I also dislike the way he jumps at Edwin when you try to get him to join your party if he's with you.
I feel like:
Minsc have been a great warrior once, one of pure good, a very nice Ranger. Then he had his accident, and he "fell": Became a lot more evil, and less cunning, making him a chaotic evil character because he cant actually stand on one side, just for the fact that he cant actually choose right. Her witch (Dinaheir, bleargh!) should deal with him so that he would follow the right path. But without a witch, in BG1, he seems nothing more than a bully to me.
In BG2 I agree completely that he's a huge do gooder, an excelent companion that means to risk himself for your safety.
Someone agree?
Flesh to stone ain't permanent, it seems.
