I had several problems with this scene, but not that
particular problem. I think I got the same choices as in the screenshot and I hated them all, not because there was no "let Wyll choose" line, but because none of them matched what I wanted to say in the slightest.
I don't think signing over your soul to a devil is equivalent to giving your life for someone/something. I think it's actually a selfish, short-sighted, desperate thing to do, because as we're repeatedly told throughout the game, bargains with devils work to their overall advantage, not yours. And their goals are never good ones. Don't do it. No deals with devils.
Can't say anything like that though.
