I'm just saying there is no clear-cut "good" option here. He's no worse than many of your own companions, including the one who's apparently the most "good".
I agree that he is not worse than Wyll (I've never considered him the most "good', always thought he was the worst). But between Karlah and paladin the good option would be Karlah. Karlah told her story honestly and paladin is lying selfish bastard.
