He wouldn't be able to kill Kakashi... Everyone Forgets he can open the gates too. He maybe can't open all 8 now but if Gai did it Kakashi could do it too. ( Sharingan can copy it )
Sharingen cant copy tai jutsu but i wonder how many gates kakashi can open u have a good point
it seems u dont know that when somebody opens the 8th gates they died when they r done using it, after all its the gate of death if im not wrong so it makes sense for the person to die
