Heeee! I don't think you have to recant - I think it's a possible interpretation of what Ukoku is doing, even if he is heretical and chakra-less, and it's really interesting - I mean, look at the amount of long comments the idea provoked.

It could be that Ukoku doesn't actually know what will happen when he pits his sutra against Sanzo's? For him it might be pure discovery. I do think he was jealous to some extent, but I don't think it's enough for him to be driven to play this long game with Koumyou. Maybe I'm wrong, but it seems to me like Ukoku's lust for something new, new knowledge or experiences or magic, will drive him to do anything.

I definitely think Kanzeon enjoys the popcorn value of the whole thing. Also, they're learning useful lessons! It's a bonus.
