My theory is based on the kishi's emphasis on the purity of the soul as a prerequisite for being the perfect host... (case in point being the 8 tails host before killer bee and the whole rhetoric about erasing all hate from the soul - falls of truth chapter etc.) so to prevent loss of self, a hosts soul needs to be pure and strong

now no one really disputes that edo madara is probably one of the strongest characters around... but can he control the 10 tails

let's remember that madara is well aware of edo tensei as an alternative for his resurrection... he even knows the seals to undo its binding effect...

Yet he wants to go through the route of gedo rinne tensei

WHY?

why does he prefer returning as a mortal when he can have powers that edo tensei can give... its cause the rinne tensei is a way to bring the soul back in its pure form (as if you didn't die) without upsetting natural laws whereas it's against the natural order to bind it to the impure world using edo tensei...

now madara knows this so he decided on the rinne tensei route... and since obito can't do tsukuyomi with his MS its obvious that madara intends to be the 10 tails host for infinite tsukuyomi to be successful...

but when he attempts it... boom - it doesn't work

essentially my doubt is can dead people become hosts... the previous jinchuurikis were made hosts but they were hosts in their actual lives... plus rinnegan was binding them as opposed to a sealing tech... i think its impossible for an edo tensei revived madara the 10 tails...

any thoughts?
