1) Since Tobirama created Edo Tensei wouldn't he be able to use a jutsu to break free from it like Madara?
2) Would it be possible for Minato to remember Naruto when he fought Pain or does his chakra have nothing to do with his soul?
1) I think he knows they can defeat Madara and Obito because Hashirama fought Madara and Minato fought Obito.
2) He wants to take control of their bodies.
So what do you think?
