It'll probly be awihle before we find out if he's dead or not. to me it sounds like he's having some sort of fight within himself beacuse he can't get over the past(what happened to obito and rin) and he's been hating himself for it. I don't think this is Kakashi's death I think it's Kakashi's trial!!! See what I'm sayin?
maybe Tsunade summon will reach kakashi and heal him.. i dont really know i have to wait for the SPOILER and i will post it the fast i can beacuse i have to made the video first and then post it ok
