sais not on the list? have we forgotten that hes officially a member of team 7? but anyways, for things to work out the way they should kakuzu has to die and hidan has to be detained for questioning on the akatsuki, since he cant be killed. so my vote went to kakuzu. if hidan is detained, im sure the leader would find a way to kill him of make it so he cant talk. not that he knows much, if they just let him in on the goal.
