They dont need the 8 and 9 tails. Havent you noticed everythings been going fine without them? And lol at the Obito fans getting personally offended about a fictional character. Somebody said the SA would just follow them if they left? How? Seriously all they need is to go somewhere for like ten minutes and not be bothered, they couldnt make that happen? What was the rush to start trying to do it in the middle of the war. What was the point of the war anyway when they didnt even need the 8 or 9 tails? I still dont get that. They got all the other juubi with just akatsuki who cant even beat the teenaged leaf ninja, why didnt Obito just go get the other 2 and not call a bunch of attention to what he was doing? Doesnt seem very smart.
As I recall, Madara criticized Obito because he rushed up the plan, forcing some things.
- Madara was supposed to be revived with Rinne Tensei.
- Obito was eager to execute the plan, he didn't want to wait more time for the Juubi to be complete. Ergo, he triggered the War to take the remaining Bijuu by force.
So you can stop blaming Madara, since he wasn't the one who rushed out things in here.
It was Obito all the way. Do you remember that the Uchiha are mentally too unstable to think rationally?
That's Obito for you.
