I've seen several threads talking about how he would fight after loosing his Bijuu, BUT, I have seen nothing really about possible changes in his general attitude and personally. Also, I have not seen the issue of him now being able to sleep being brought up in any of these conversations. He has been an insomniac his entire life, but now he can actually sleep peacefully. What kind of effect would that have on him? Also, what kind of effect is he getting from not having to worry about going crazy? Please discuss.
