Even in previous versions when you can't free her, she still shows a bit of appreciation when you've tried. In general, from what I've seen, outside of her deep hatred of Giths and Selunites, Shadowheart can be somewhat pleasant.
Yeah, even in previous versions, she reads as a basically decent person who has been fed a load of BS on Shar, Selune, and the like.
Which, to be honest, is par for the course with Shar. That's a goddess with a long history of luring people in and chewing them up in a way that has her victims saying "thank you for devouring me / ruining my life"... even other gods.
