What I want to ask is that,
Madara could control the movements of 9tails when he fought against Hashirama
Obito could control the movements of 9tails and make it work however Obito wanted.
Obito controlled Yagura's movements.
Itachi never controlled anyone but he at the end made Kabuto teach him how to stop Edo-Tensei.
The question is that if all of them could control a person using Sharingan after catching an opponent in it.
Why was Sasuke using Genjutsu on Danzo(to trick him into believing that one of his eye is still open) when he caught him with his eyes instead of controlling Danzo's movements and make him kill himself?
Does he not know how to control an opponent's movements?
