You create life, a life is lost [that's the rule of samsara]
Nagato knows that and he ain't a fool to die for someone
I think rinne tensei has been retconned since Nagato first used it. think about it, nagato also said it was too late to save jiraiya, yet madara was planning on getting revived decades after he died. Kishi simply changed the requirements for the technique.
truly now , I think Nagato after used Gedo Mazo, with all those spears in his back , he couldn't fight himself, so he needed troops (deva pein) to use his rinnegan jutsus.which was made possible by yahiko's body ..My opinion , may be wrong ....:eww:
