Obito is the true bad guy and NOT Madara?
- the Infinite Tsukuyomi/IT; an illusion cast upon the world so that everyone can live in their own dreamworld that consists of peace.
- becoming the Jinchūriki of the Juubi/10 Tails and cast the IT on the world.
Nagato was the one to revive Madara but as we know he "betrayed" Tobi/Obito and Madara on that.
So in order for Madara to use IT it's required to be in a human living body as you can't become a Jinchūriki.
We all know that Obito wants to "see" Rin again, well, that won't be even possible anymore as he himself said that he'd die when he uses the Rinne Tensei if he revives Madara.
He wouldn't be under the controll of this genjutsu as he'd be dead = no Rin for him, right?
I got the suspicion that Obito is well aware of that and he got some other things planned, especially last chapter showed that Obito knows how to play his cards against Madara.
Also, Obito wants to show Naruto & the other Ninjas what despair means, why would you do that if you plan on putting the whole world into a fake peace world anyway? That's odd.
What if Madara is trully the one seeking for ultimate peace (in a wrong way) and Obito for something different?
I just felt i had to throw this in.
