Obito is the true evil mastermind of the manga.

[Kikki]

Oh and to add that, yeah, he was turned around and influenced. He wouldn't have developed the way he is but.... he made quite abit out of that influence. Too much to call him innocent, especially with how he is acting on the battlefield NOW.

Obito might have been the one who set in motion much of the evil events in Naruto, but if he is being used by Madara then Madara is the "mastermind". Just because a person sets events into motion through their own action, doesn't mean he is the mastermind. Obito only acted in order to set in motion Madara's plan.

Although at some point he realizes he can act without Madara, and now seems to be rebelling... At first he was used by Madara so I'm going to say Madara is the mastermind, and Obito is a rebellious henchman.

 

[SenseiMartian]

I mean, he carried out many of the deeds, but his goal at Naruto's birth was to retrieve the Kyuubi, which was probably to aid in the "Moon's Eye Plan" that was given to him by Madara. So in my opinion, Madara is the true mastermind; Obito just carried out the directions given to him by Madara.

 

[Bogard]

I agree with the title but not the topic. Obito is the best evil mastermind in the manga true, but not the greatest villain. That one is Orochimaru(i hope he doesn't get trolled with his backstory though)

 

[Neon Indian]

Oro knows more.

 

[H a n]

He was molded into nothing more then an avenger/ peterpan that wanted to make his own world and live forever.
