Re: Naruto inherites the Rinnegan (partially) from Nagato....Why?
...How could you come to this conclusion? Not to sound offensive or anything, but Nagato is not giving Naruto any doujutsu or jutsu. Nagato is the way he is because more than likely he was injured long ago (recall the report Jiraiya got that said they were attacked and killed); or thats the cost of great power (Kishi's equalization).
Nagato isn't dying now, but he is weakened by using this much chakra from the battle and is feeling the effects...Note how he says "Peace is so close", and understand that he knows that he is feeling the effects but wants to stick it out longer to accomplish his goals.
If anything, Pain is trying to get Naruto to his way of thinking (just like any villian does with Naruto before he chooses his own way of thinking) so that he can get the Kyuubi. Nagato is not searching for a successor of the Rinnegan in Naruto, he wants whats in his belly.
