Karlach is one of Baldur's Gate 3's most beloved characters—and for plenty of good reasons. She's big, has potent golden retriever energy, and can probably bench press me—but she's also, like a lot of the game's cast, spectacularly well-written. Her journey of betrayal and punk-rock redemption is compelling and moving, to the point where the lack of a "perfect" ending was a point of controversy.
Broadly-speaking, I'm not on that particular conspiracy train—while I think from a critical standpoint the game's ending at launch felt a touch thin, that was later solved with a massive epilogue patch.
