Obitio's Biggest Mistake Or Perhaps his real plan all along.
Was letting naruto come inside,Im kidding
It was Waging War, Telling everyone his plan and so on.
Did he honestly want to go through with this plan? Or was
he trying to screw up Madara's plan from the get go?
If He was really after the greater good with that plan he would have just continued how he was before hand.
He would have gotten the 8 tails and 9 tails eventually. But his impatience pushed Naruto to master the 9 tails.
If he would have just sat back Sasuke and Naruto wouldn't be as strong as they are now and they would have fought
and beat one another.
Itachi would have been out of the way now that he died, And HE would have Itachi's eyes.
He would have gotten the 9 tails chakra from Kabuto in Trade for Sasuke After Kabuto shows him the Edo of the Gold and Silver Brothers. Then he could have summoned the Ten Tails in it's incomplete form at anytime and easily went after the 9 Tails if he wanted Or simply summon the God Tree in a faraway land so NO1 would stop him.
I could never see obito just going back right after Madara died and left the Plan to him.He couldn't If you forgotten Madara stuck that failsafe in him and Zetsu was there always keeping an eye on him. I bet you anything Madara's "Will" would just have killed obito the moment he did step against them. So Maybe this whole time he purposely put the world at war and when the chance came he took the Ten tails so He would be in control and not Madara. Obito never saw eye to eye with that man even when he agreed to help him.
If you haven't noticed, Obito never stepped out of Line ONCE against Madara until The very moment he got the chance to grab the Ten Tails. Even right before you see he was mocking Madara like they both were in it for themselves before they got detached from the beast.
