My first impulse was to give to Baelen and when I heard the misogyny that flowed after I regretted my decision and reloaded.
It's an interesting quest but I think good outcome relies on moral luck. From the conversations in the underdark it seemed equally likely that she would have remained as a battered wife losing both her income and bodily integrity. And Balen gave the impression of a "happy slave" - absolutely being exploited but happy in his simple minded way.
So, yes, in this narrative giving the stalk was the right thing to do but there were plenty of reasons to believe it was the evil choice.
