It makes a hell of a lot more sense than the Nere interaction that was in early access where you could convince someone who is far more chaotically evil to take a step back from the Absolute worship. Especially since he doesn't join your party afterward and so would go straight back to being mind controlled. The entire reason it makes sense for Minthara is exactly because of how you already recruit her. She has a scene at Moonrise which you then rescue her from. All anyone is saying is that if she is not killed, that scene should still play out the same way it does if you ignore the Grove conflict entirely. Because it doesn't make sense for it NOT to. Nothing about the game visibly changes, just one programming quirk that counts her as dead if you knock her out which makes far less sense.
