Yea that seems likely...he really doees need to take control.
But what kind of agreement do you use with an a Chakra monster that in reality could destroy you?
Me 2...it could be one of his greatest jutsus if he learns how to controll it fully like Killer Bee. cuz that would just throw away Sasuke's Genjutsu. Then Combining Attacks with it Chakra Would be devastating.
