I think like with the other companions he should at least have a default decision without the MC's input, as I'm sure others have said. If he was allowed to make his own choice imo there's no way he wouldn't choose to save his father over himself. I've always told him to end the deal but I don't believe it's what he would choose on his own, and I think it would make more sense as a persuasion option. Then again maybe this is an intentional characterization decision for him? That he's so unsure of what to do in the moment that he in a sense lets someone else choose for him, or at least follows whatever advice they offer.
I agree. The single worst thing for me about Wyll is that he's unable to make his own choice in this scene. If Larian is winding down on making narrative changes to the game, this is the top thing I would choose to add for Wyll. It's weird that he's the only one without a default choice/agency. And if it is intentional characterization that he's so unsure of himself, there needs to be at least some dialogue lines where he expresses this. Otherwise it looks accidental. And there also needs to be some kind of resolution to his uncertainty, or else it looks like an unfinished story. Given all that would need to be done to make intentional indecisiveness convincing, I think it is easier for Larian to just give him agency.
