When will she come around(or at least start to)?

I am currenty doing a "good" run and I saved Minthara at Moonrise and i heard that she will eventually "mellow out" a bit and start to see my point. Similarly to Astarion who craves power and all that,but if you talk with him enough he will see that doing good and being nice isn't all that bad,and that "power isnt freedom" and all that. But Minthara? He is still on that "we will control the Elder Brain" train, and i dont see her at least getting closer to my point of view. I dont expect her to turn around 100% but I would like if she moved a bit. The only good bit from the conversation was about her choosing who to let close and that deepens the bond with the she does. Otherwise it does not look good. I was aware that she is "evil aligned"/ruthless,but I also saw the she can come around. I am in act 3,didnt do all that much quest. Will she ever be just a tad bit less ruthless?
