Not impt why Rin died? Are you kidding me? Rin's death was the main reason which spurred obito into doing what he did which in turn set off a chain of events across the entire world and there you are just dissing it like that? Seriously have what have you been reading?

@Yoru I like your idea of obito changing his plan from that of madara it would make sense and his statement of saying 'you were supposed to use the rinnen tensei for me' referring to Rin. Which brings up more questions of the extent and limit of that jutsu. Who can or cannot be revived by that jutsu. I mean if he was intending to revive Rin with that, why wasn't jiraiya revived at that point?
