Why madara needed negatos gedo rinn tensei

[Ero sennin]

in chapter 453 madara says he needed negatos gedo rinn tensei jutsu i may have worked out why. i think his original intention was to compleate the ten tails and control it like he did with the nine tails makeing him powerful again. what he is doing the now i think what he is doing now is his effective back up plan to become a jinkuriki to gain acess to his chakra to control the shinobi world. his orginal plan was to use negatos rinn tensei to bring the ten tails back to life through the collected energys in the statue. so he could control it. since naruto has put a wrench in his plans. he has to seal it into himself to become whole as he says it.

what do u guys think?

but why would he only want to bring it to life when he has the option to put it in himself? if he brings it to life, he may be able to bend it to his will with his sharingan, but if he's the ten tails jinchuuriki, he'd be able to harness the power himself.. have advanced healing, limitless chakra.. i'd say it beats walking around with a giant ten tailed beast..

old, even though he can dissapear he might die.

So as we know nagato died due to exhastation,bringing back all soul after using chibaku tensei(plus the useless of shizune). so that could mean madara could have been revived before. One soul could waste so much chakra.

[Valkyria]

Madara probably wanted it as a life-assurance policy or perhaps he needed to die in changing to a body that could hold the Juubi's within himself. Nagato would then revive him into whatever body that is. It's a possibility

[Naruto X Vasto Lorde]

maybe he was trying to take a new body sorta like orochimaru but better
