That one is plot no jutsu.. Madara had no reason to fight Hashi anymore for it was time for him to initiate his Tsukino mei plan so he decided to foderise the whole NV and its bijuu so he can get on with itSo did Zetsu !!! does that makes him stronger ?

Because plot.
Because he can't beat him without stealing his power.
It was because Hashirama was immobilized due to Madara's Black Rods. Otherwise, Hashirama would have put up a fight and Madara would have lost easily.
lol?
We all know harshi is no match for him
you're hope less Hashi > EMS Madara+ KyuubiWrong
EMS Madara=Sage Harshrama
Then When edo Madara was fighting harshiram he was Fused with harshirama life force snd renninegun
Harshiram is no match for his fusion with reninigun
Hashirama fought against Madara and was able to immobilize Madara even when he had the Rinnegan. Revived Madara didn't have Rinnegan. We all know what's gonna happen after that. Lol
