Obito was the only Uchiha to be a Kage

[Son Ryuto Uzumaki]

Why did he leave the Leaf then

Because his people would not listen to his warnings of a foreseeable genocide

 

[Son Ryuto Uzumaki]

Itachi was Kage level at 7.

yeah lol who wouldn't be compared to Hirushit

 

[Six Paths of Logic]

Nope. Wisodm of a Kage at 7=Kage level

You're a terrible Itachi Fan/fapboy.
Even though Itachi didnt become a Hokage or a Kage he was still a great Ninja from the Hidden Leaf Village, he has done a lot for it.

What are you... Mark Sanchez's brother?

 

[VongolaX]

Ya, he was mizukage to spur up akatsuki's birth place and find details on Rin.

Madara had Muu and oonoki swear their allegiance to the leaf.

 

[Goetia]

Why did he leave the Leaf then

Because the Uchiha were being oppressed and he was betrayed.

OT: It doesn't work that way. If someone were to put another under mind control, does that make the person that has the other under mind control that person? No.
