i bet sasuke will kill him b4 the synk wit gedo, he just dosent have a way of killing him yet.and ive read the theories about the dark figure that surrounded sasuke, there is a 55% to 45% ratio in my opinion... 45% being the figure was a representation of how evil sasukes aura or chakra has become, then the 55% would be the posibility of the evilnes and rage of sasuke being related to jugo basica
