nope madara had already given his rinnegan to nagato for the sole purpose of coming back and obito wasn't there when he did that . .thats y he created zetsu in first place . .he wanted zetsu to contact nagato at later point of time and convince him to revive madara. .he replaced zetsu with obito to make sure he would never fail. .
He couldnt use black zetsu inside Obito if he wasnt edo or alive,therefore his plan failed.To be honest his plan failed once again when Nagato died and Obito casually tooks his eyes and had no intention of reviving him.Kabuto messing up with Obito is the only reason edo madara is in the battle field.His was full of holes,even if Nagato had revived the guy he would have been revived in the state he was before he died,a crippled old man that thing cant handle the Juubi.
m talking about the zetsu(hashi's DNA+ madara's will) which madara created before he met obito. .he did not simply create zetsu for nothing . .he created it for his own good which is to befriend nagato. . i agree his plan of coming back alive failed with the death of nagato . .still obito wanted to revive madara . .as a proof watch konan vs obito fight wherein he states that RT which nagato used should have been used for his purpose. .and if nagato had RT m sure madara would hav come back @ his prime. .because nagato would hav used most of his lifeforce to revive madara @ prime
it's madara ofcourse. . obito was simply doing wat madara told him to. .

fair enough.Him being mad about Nagato betraying him i think has to do with his past(Kakashi not keeping his promise and stuff),since he didnt show any concern after of reviving the old man after and was pissing his pants when Kabuto showed him Madara.About RT there is nothing suggesting that he can bring Madara back in his prime how is that even possible.The only reason his body is in his prime is because of the Kabuto modifications.
Obito never expected that nagato would die. .he got pissed when he saw madara's body because he had changed his intention of reviving madara after nagato's death and also there was no one who could revive madara besides nagato . .he was pissed because madara would become invincible if he's revived via EDO TENSEI and there would not be anyway to stop him. .
madara would hav surely come back with his prime body . .because nagato would hav suffered major damage of using RT . .obito was on way of his death as a partial impact of RT and not full . . And this is how RT works . .it consumes life force of the user. .depending upon the age to be given to the person user intends to revive user will hav to sacrifice his lifr force. .in worst case user will die instantly which happened with nagato
but still my point stands Obito had knowledge of everything,Nagata Zetsu Madara.when disconnected from the Mazo if Obito had gone back to the village and transferred that knowledge to guys like Minato and Hiruzen,this war would have been avoided since the main threat was out of the picture and zetsus and Nagato could have been dealt with?am i wrong?
Lol . .that would hav been possible if obito hadn't gotten manipulated by madara. .it was too late for him to do that . .because he evidenced rin's death and changed himself before madara told him about nagato and rinnegan. .
Manipulated or not,Madara gave him candy it was his descision to take it or not,nobody forced him.He took it this war happened if he handt,a Kage summit would have happened earlier,precations for the safekeeping of Jins would have happened earlier and a nice bounty on Nagatos and Zetsu head.
that did not happen . . deal with it. .
i am not saying it did.....
but wat u r saying is completely opposite of wat kishi wrote. .
what i was trying to say,was that Obito descision led to this thats all.
