Has anyone managed to find any kind of proof that the paladin of Tyr is who he says he is and he's not sent by Zariel? Or was the decision you made to help him or Karlach based on your character's alignment? To me, it seems there is not much room for a rational neutral mind on the matter and it's pretty sad. There should be some hints here and there as to what the real story is. Or did I missed them?
You missed them. There were several things that felt a bit fishy, most importantly the effort made to tell you there's a corpse under the trapdoor. Stepping back a moment, the choice is for every quest to be clearly spelled out or for some of the quests to be ambiguous so there is the potential to be wrong.
Despite myself, I ended up liking how this played out because of that; the way I originally approached it was completely flipped on me because my assumptions were wrong.
That said, if you decide to kill Anders et al, there doesn't appear to be a way to end the quest. I've tried every combo of dialog she offers; I've tried healing her; I've tried asking her to join me ... Maybe because I told her I'd kill them, told them I'd kill her, and then instead of bringing them her head told anders I was siding with her instead.
