1) Eh, this is splitting hairs to me (hate, strongly dislike, close enough) and that it is a mysterious attitude in contrast to how everyone else seems to feel about the Sorceress. I think we're supposed to wonder about it.
2) She wants to kill the enemy and ask questions later, which to me is blood thirsty, even though I'd say it was righteous considering she wanted to kill a clearly hostile attacker.
3) I don't disagree, although no denying it was provocative on the part of the storytellers too.
RE the Sorceress's influence on all of this, I am sure that could be an answer, though I hope there's more to it still since everyone has guessed that just about.
