There's also the issue of her being an origin character, so this story has to make sense from her perspective as well. Do you have to kill the cultists if you are Karlach, or can you just run away?

My guess would be that if you choose to play as Karlach you're given the opportunity to spare them, but the game and her story will heavily lean towards making you kill them.
Essentially giving you the choice but still heavily suggesting that your choice isn't 'intended' or canon.
