so, alot of talk about this. but here are some good points to be made:
Itachi cant use izanami to end ET. he told Sasuke he'd talk to him and he'd explain the truth. If ET ended Itachi would disappear and Sasuke would just continue to go after the leaf village which, im assuming, Itachi would like to prevent.
Izanagi, turns reality into illusion. Sasuke had crushed, slashed and burned Danzo and his body would fade into nothing, like it never happened. So in opposition Izanami should turn illusion into reality. But then again, is this truly possible? If that were the case, Itachi could have taken down "Tobi", Kabuto or anyone else whenever he wanted, avoiding this entire war. He could have used it to take down "Tobi" when he first discovered him.
A good point has been made about losing his sight. as long as ET is active, Itachi should just regenerate back to his prime state.
A good question, if Itachi can turn things into reality, could he not just bring himself back to life, or any other dead person? Could he make an illusion of him copying any jutsu of any ninja known and make it real?
With all this in mind, we can expect an amazing chapter next week xd
