I think you misunderstood what I meant by "BG3 was originally supposed to be much darker", I meant that originally instead of Balduran there was Daisy, who according to some people was removed because players were afraid of her, and according to others because Larian didn't like dnd 5e and wanted players to use MindFlayer's abilities, even though there are only a couple of useful abilities there. And also the fact that most likely the original canon character for the game was Dark Urge. And some of the cut content for Minthara also hints that the game was supposed to be darker. That's what I mean, and not the Karlach story at all.
