As the title says, in edo mode, he was able to allow himself to be bisected to use his izanami, maybe it was necessary to use the jutsu maybe it wasn't but it seems to turn out that edo itachi used that moment to use the izanami technique. However, if he has to allow himself to be hit that way and he was actually alive, he would not have been able to beat dragon sage kabuto at all. Especially with the fact that they needed to force kabuto to release edo tensei and not kill him.
What are your opinions?!
Sasuke was obviously holding the guy back. Example;
Instead of jumping infront of sasuke to save his ass, he could have protected himself and not take a few stalagmites and stalagtites.
Instead of using susano'o to protect sasuke during white rage, he could have protected himself.
Instead of assisting sasuke against the orochimaru mode, he could have protected himself and not get an oral-rebirthed-bisection.
Instead of wanting to capture kabuto, he could have just killed him, and even used amaterasu to burn him
Instead of using yasaka magatama to hit the cave ceiling, he could have used that oppotunity to hit him, then blow him to bits with susano'o while he's incapacitated
and on and on and on.
So, Yes.
