I'm starting to seriously worry about suu's sanity. What's with all the memory losses

I could be wrong but I think Saharah is erasing Suu’s memories after he feeds him people because if he knew he would leave.And I think Suu has a part of Saharah so he can manipulate him idk Sahara’s true intentions are though.

Yeah, would be nice to get a glimpse on Saharas true intentions. It can 't be that he is just horny.
