I bought this game because of Karlach specifically. Was so excited to go on an adventure with her and come out of it swinging. But I can never get that chance because the game won't let me.
In a game that was advertised as one where you craft your own fate through your own actions, I should be able to find some way out of her predicament.
This idea that only having a "tragic ending" for her is fine as a narrative vision makes no sense.
Her goal in the story is to escape enslavement, yet that is not possible while that engine is still inside her, because it is constantly anchoring her to her slavers. Her arc can never be completed because of it. That's not up for debate, and it's not a matter of "vision". That's just the logical sequence of her story.
If you wish to tell the story of a slave who seeks to escape enslavement but fails, there needs to be a different setup for that. You'd need plenty of hints throughout her story that escape is futile -- that every avenue that should be open to her somehow isn't. And those justifications need to be good and convincing.
However, I fail to see how doing that is even plausible given all of what the other characters have been able to pull off in their stories.
