1. I see him dead either way and attempting to take himself Madara and the Rinnengan down, but only succeeding in destroying himself seems to fitlol
1. Why suicide?
2. I see that happen that he saves naruto with getting kurama back / give kurama to naruto the half he has
3. Why trap himself together with madara if he can trap only himself there, or only madara.
I can totally see him using Rinne Tensei on Naruto.
But it would be useless against Madara.
So probably he will find a way to take at least full Kyuubi (chakra tug) and give it to Naruto.
This could also kind of unbalance Madara Jinchurikki form.
