guys i was wondering how madara is making obito perform rinne tensei, then i remembered before madara died he injected his will into a zetsu so half of it was white (hashiramas dna part) the other half was black(madaras will) . while obito was about to perform the jutsu his body went half black and since madara had to put hashiramas dna in obito to enable him to survive i think madara also implanted his will in obito and smehow controlling him? just a thought not sure if anyone alredy made a thread about this
