Nah, that would make the manga pointless, having Madara win would just be bad writing.
Having the bad guy win requires it to be set up early on so that the stories of the characters are complete by him winning, but in this case it would leave everyone's story incomplete and just be a troll.
If this manga ends like every other manga where the good survive except some fodder and there's no real major struggle I wouldn't be happy about it but w.e.
