Think that's why obito will die using rinne tensei on madara...to take him back to him prime....remember nangato revived a whole viallge (as they were at the time of death) but he could do that maybe die to uzuamki bloodline (strong life force)
even for revival of the dead there are limitation as to how far back you can revive someones age but in naruto things that seem impossible have been made possible thats fine by all point of perspective but i honestly think madara will not be revived to his desired age if he is even revived because of obito giving him attitude about it basiclly madaras being used as a control for juubis power but if madara or obito are killed madara is out of luck with any option to be fully revived period
