Hey y'all it's time for my favorite segment "I had a thought and I need to vent it out among like-minded people in a lot of letters".
I think it suddenly dawned on me why Karlach's doomed story feels so much worse narratively for some players (like us) than other doomed videogame characters, lacking quest being just an additional insult to injury. This little something that I think a lot us mean when we say "it's unfair", but not really articulate. hence people thinking we just want sunshine and rainbows.
Will hide under a spoiler 'cause it's big, likely spoilery, and also, well, heavy death-related topic incoming.
Like, we've seen people saying that actually her storyline is great because it's a good representation of loving a terminally ill person and such - and I think in a vacuum most of us agree, it's heartbreakingly written and very well acted, it's the setting and the quest that bring some major disbelief in the mix. However, we've also seen actual people with heart problems come up and say that it feels bad to not be able to do anything even in a videogame.
We've talked about Thane from Mass Effect, whose condition is never a part of his quest and is just a fact (that Shepard can make peace with and romance him as such), and about V from Cyberpunk, whose whole game is exhausting all available options before the inevitable dawns on them. As mentioned, Karlach's situation is neither "you aren't even supposed to help, it's just life", nor "you can fight for her with all you've got", it's in the middle, and it's frustrating.
HOWEVER. Hers is also a tragedy on top of a tragedy. V, Thane, some suddenly killed off characters like Joel, they've all lived. When we meet Karlach, even before we know she's dying, her story is already screwed up enough. Sold, mutilated against her will, forced to fight in a war for 10 years with no companionship or touch, all that good stuff. By the time we (as a friendly Tav or such) learn of her story we're already pissed and hurt on her behalf much like when Astarion opens up about his. Her life up to that point is already incredibly tragic.
So when you stick a terminal inevitable illness on top of that, you get not just a character dying after a life full of experiences and mistakes and whatever, you get a dying character who hasn't even been living for the last decade. That's somewhat - not directly, but somewhat comparable to kids and teenagers dying. Not to infantilize Karlach, of course. I mean this in the same way Sam means it when she talks about Karlach regressing to the age she was last herself at, which is no older than 18 by their estimate. Because she doesn't have any proper living experience past that point. So in terms of, you know, looking at some teenager's grave and instinctively thinking "Shit, man, you haven't even lived..." - that's approximately the same painful note that's present there when you look at Karlach. She isn't just losing her life, she loses it almost immediately after not having had it for a decade.
And sure, some people are sick from birth and never grow up, and that's also a real existing tragedy (regardless of if 'real' tragedies even fit in d&d), but we know that Karlach was a healthy kid, we know that her condition is manmade - even if it wasn't, however... An adult dying before their time after having lived a life is a tragedy. A person dying before they even get to live properly is an even heavier tragedy. By itself.
And all that weight (which is harsh enough for a lot of people) is dropped on top of an already sufficiently enraging story that makes us rally for her. An unfairness that technically can be compared on an emotional level to a teenager dying is attached to a very much adult woman already robbed of her life prior to that. It's not just a tragedy, it's a double tragedy sandwich, maybe even triple. That's not just 'what a relationship with a terminally ill person feels like', that's a traumatized ex-slave with CPTSD and a huge gap in lived experience (which is already more than enough on one person) who is also, on top of that, dying tomorrow. That's a conscripted teenager coming back from war as a traumatized adult vet and dying in a ditch because no meds were made available to them.
With her only other option being "get MORE traumatized and CONTINUE to grow that gap in your lived experience - but this time a person you care about will do it with you (you don't want a person you care about to go through that ever)".
That's a little bit too much of a "real life" for one videogame character in a fairytale world, don't you think.
And then on top of that her quest lacks. On top of that her friends and/or lover aren't doing squat for some reason (they're getting railroaded). One of her abusers dies in the most anticlicmatic fight of all boss fights in the game and the other is never addressed, period. We aren't even doing justice to her past trauma, let alone the ongoing one.
Like, Karlach is right. "It's enough! It's ENOUGH." What happened to her was already enough of a tragedy. And because of specifics of that tragedy (not living for 10 years) the second one (dying) feels ever worse than it would if she was, like, an adventurer of the same age who at the very least had her time under the sun.
I would put a TL;DR here but I'm not sure how to even phrase it. "Actually, if you think about it, Karlach's tragedy feels worse than some other similar characters or even real situations not just because of the quest lacking or there not being a happy ending, but because it's multiple incredibly heavy tragedies stuck on top of one another in a tower higher than any other character and it's too much when you can't do a thing about any of them"? Something like that.
