The thought process brought me down this line of thinking so I thought I would share!
Ok, so the Gedo and its particular role with both Obito and Madara. We know the Gedo is responsible for keeping Madara and Obito alive, but it makes me wonder if perhaps Madara and Obito are not speaking as themselves, considering their connection to this particular statue? Remember Madara is obsessed with power, and we know that the statue still possess the ability to artificially keep people alive well past their time (as we saw with Madara). My wonder is, what if the Juubi's will is coming through both Madara and Obito?What if what we are seeing is not so much their respective personalities, but personalities that have been distorted over time?
Consider Madara first, he had done some various crazy things to obtain power, down to the point of sorting out how to unlock the MS, and even taking his brothers eyes. If I build off my last theory and what we see in the sharingan is the unpurified power of the Juubi, then perhaps that still links Madara (and others) to the Juubi's consciousness? My thought here is that what we saw in Madara, was not his will at all, it was the will of the Juubi itself!
Then consider Obito, his initial conversation was that he was "a shell of his former self" when he talks to Sasuke, then he goes on with a conversation with Naruto stating that he is collecting tailed beasts to "become whole again." This change in Obito started taking place when he was trying to get to Kakashi, he noticed somthing strange with his Sharingan then (but not again when he got close to Kakashi). The idea here is once Obito saw what he thought he saw, it was no longer Obito inhabiting that shell, it was now the will of the Juubi, which sought the destruction of the world!
Finally, we get to the conversation where Madara talks about how Nagato was supposed to resurrect him with the Rinnegan, however there are inherent limitations with the Rinnegan and no actual knowledge of the real Madara and that agreement! in fact we hear from Obito that HE was supposed to be resurrected by Nagato when he spoke to Zetsu ( who knew who he was from the start). This further leads me down the logical chain that both Obito and Madara were not their original personalities through the series, but were shells of personalities being controlled by the Juubi.
I would argue that even Nagato was more literally a puppet of the Juubi, though having conquered some of the Juubi's paths, he remained trapped by the hatred he held after Yahiko's death. That trapped him in the Deva path, and kept him from full enlightenment, meaning when he was injected with those chakra rods, it was a sign that he was no longer himself, but being influenced by the Juubi's twisted logic..only at the end was he able to surpass that path, and find pure enlightenment through Naruto before he died (I say that because in the end he used his life force for the massive jutsu, not his chakra which was tainted imo).
To sum it all up, ever since the Juubi was sealed by the Rikoudo, it's been scheming by projecting his will on the uchiha from the very first day the Older son Inherited the sages eyes... Because of his hatred for his younger brother, the rinnegan that the sage had passed down begun to be affected by his hatred (juubi's will) so that down the line, juubi manipulated the uchiha's hatred and finally converted the Rinnegan into sharingan... so that in other for them to gain strength, the Uchiha's would begin by killing their best friend, then taking the sibling's eyes and so on...
Eventually, influencing madara to have the idea to resurrect him (the juubi) so he can rampage the world once again... so juubi will become the final villian... He'd being the villain behind the curtains all this while
Just some thoughts
