TLDR: Gortash should have had an optional redemption route exclusive to a Durge run
i've only seen a few people talk about it, and it really is extremely sad to me that Gortash has no redemption path. he really is the bad ending version of all the other characters' cycle-of-abuse backstories. SO many bg3 characters can be saved from that, and a huge point of the game is how you can be more than what your abusers tried to make you be, and that doesn't happen for Gortash. no matter what decisions you make he has a bad ending, suffering eternally at the hand of his own god.
it's just so odd to me the way that was handled: ESPECIALLY in a durge run. i understand being unable to redeem him in a normal Tav route; he doesn't know you, why would you be able to give the help and support he needs. but in a Durge run, you two were clearly *so close* to the extent that when you arrive, he shows genuine joy at your arrival, calls you his "nearest and dearest" and has MANY other lines showing that he deeply trusted and respected you pre memory-loss.
they also give you as the player proof that durge felt *the same way* about him with things like the prayer of forgiveness letter they wrote about him: "Forgive me Father, for i can't help but admire the Chosen of your sworn foe..."
Gortash meant so much to durge that they were genuinely having a religious crisis over caring about someone and something that wasn't their Holy Father and his plan for you to kill everyone and end the world.
he cared about Durge when they were fully under their Father's control. he cared about Durge when they come back as an amnesiac. he keeps caring, even if you choose to reject your Father. he tells you you'll never be a servant, that he views you as his sole equal, that now that you have returned to him he wishes you two to rule together as one. and if you reject him or side with him, his fate is the same, and you barely acknowledge when he dies. it just seems so counter to the rest of the game and its messages. i know a lot of content was cut and changed in act 3 and that a lot of people, myself included, felt like the end of the game fell flat compared to the earlier parts, and Gortash's utilization is one of the biggest examples of that.
(sorry this is a bit of a mess lol i have strong feelings about this and his story is such a tragic waste)
