I feel like the only one on the Yuji's side right now
I think he was just happy to be abble to show up at Shana and meet her for last time, his thoughts surelly were something like "It worth dying and sacrificing for this world?" and then when he found with Shana was like "Yeah, she worths it". Besides we don't know if this distorsion is gonna destroy the reality, it's like a 10% chances of sucess, and he believes in that. I gotta say that after all what he did, I'm still on his side and will be on his side till he realize that he is doing it in the wrong way or get to his goal. Just my oppinion ^^
