And yet, you all seem to have missed what Karlach wanted herself.... She wanted to go out on her own terms.
I think going out on her own terms can be (and IMO should be) considered a failed state. Like once somebody knows there's nothing else to be done to fix the issue, obviously they would want to go on their own terms. The issue is that there's no in-between, like a huge chunk of narrative is just missing
You can turn her into a mindflayer, from one sorry state into another. You can persuade her to go back to Avernus, a place she truly hate. Or let her live life to the fullest the time she got left, and just be there for her in the end as she asked if you would.
Larian expanded on going back to Avernus so it became a better, not the perfect rose smelling some want, but yet a better one. If you check the latest interview with Swen, and where he talk about how that was done. I don't really see any other game studio out there do this fan service in such a short amount of time.
I'm sure in due time modders will offer up a lot of endings that will suit everyone's whims. They just won't have the VA work to go with it.
