I don't like Orin but damn can she not get a break. Everyone just going on and on about the Durge being a miracle, how much Bhaal just loves them sooo much.
You can really tell why she despised Durge. It's like no matter what she did she was never going to be able to match your raw ability and her vision was never going to match what Bhaal wanted. It has younger sibling in the older's shadow energy to it.
Apparently Durge also had a lot of hubris and didn't see Orin as a threat at all. She does come off to me as very childish. Like she's throwing a temper tantrum, running around breaking her toys, etc. Which makes it even more of a dig when Gortash says he tolerated Orin, like he's tolerating a badly behaved toddler, but he liked you. He never saw her as an equal the way he saw Durge as one. (And still does after you come back.)
Even cozying up to gramps Sarevok and his murder club he's just savage about Orin. Wants to invite you back for tea after you kill her and everything.
Even random Bhaal worshippers in the temple are begging you to kill her. It's pretty wild just how much everyone hates this woman.
