I've now gone through BG3 for the second time, and this time I had Karlach in my party and saw her ending. And man, it's such a great ending for such a great character, very dissonant with the character himself. But people on the forums are whining and asking for it to be redone because you see it's too sad and violent. People seriously what's wrong with you this dramatic ending (in my case with her death in the finale) perfectly suits this character, yes sad, but so and so should be, that's what the developers wanted to achieve, that was their idea. Such a cheerful and positive character with such a tragic ending, it's great, a very strong emotional moment with her death, which works just as well in many ways thanks to the fact that fate is an evil bitch and unjust to such good people (just like in real world, right?), it can not always end well and everyone will live happily ever after, it's just not interesting and boring. Considering BG3 was originally supposed to be much darker, this storyline fits it perfectly. But no you want to ruin all the hard work of the writers by demanding a happy ending for her, seriously? I understand if it was buggy or unfinished, but no there's nothing wrong with it, so why change anything?
