It's not his fault he's like that. The CCG made him this way. The intsances of which he did remember his past were extremely painful for him. He's in a very fragile psycological state of mind at the moment, and it would be in his best interest for him to not fully remember his past right now.
I liked Kaneki before he changed. The F***! He's back where he started with the stupid denial/thinks-he's-still-human phase...
Geez..... I hope he remembers soon.
I wonder where the CCG gets Sasaki's "FOOD"......
