Madara had to have given the eye he stole from Kakashi back to Obito. Why? who knows.
Now I don't think Obito has a deathwish in his heart. Im pretty sure theyre stemming on the fact that Madara placed a seal on Obito's heart that prevented him deviating from "The Mission." I believe they said Obito got into that fight with Kakashi in the other realm and intentionally allowed him to use his Chidori and pierce him through the heart. That removed the seal and Helped Obito become the Juubi Jinchuuriki.
Naruto apparently can heal anyone with his 6th Sage Senjutsu. I believe hes simply unable to repair his heart to make Obito feel human again. With this reality, he says He'll die to help save the world.
I think Sasuke has the power to get back, He just doesn't know how.
Also Obito should get a Susanoo. But lowkey, I think certain fans will agree with me, But i believe Obito deserves the Rinnegan. Unless someone is willing to argue that you need EMS First. Hes been cultivated with Hashirama's Cell since his accident and now he finally has both of his eyes again.
The true question is, What is Kakashi's role?

- to simply go back to the real world, that is. since Obito is in other dimension with sakura and naruto, he needed kakashi's left eye to go to that dimension and with black zetsu in the left side of obito, Madara needed to give Obito back the left eye so that BZetsu can control Obito to get back to the real world.

- I contradict this theory because Sharingan is unique per jutsu. For example, Shisui's eye has the power to control the enemy without knowing it and Obito has the power to go to other dimensions. Does anyone else's has the power like these two? No. That is why when the series revealed that Kakashi's and "Tobi's" has the same power, it is already concluded that the masked man "Tobi" is Obito.

- I AGREE! Hehe, Obito should have a Susano'o too. He's an Uchiha right? And maybe, just maybe, he will be given a chance to have a Rinnengan because of Hashirama's cells. Kakashi's role? Well, if and only if Obito will die, then I think he will give Kakashi his both eyes now. But it'll drain Kakashi's chakra much more faster, he is not an Uchiha. hehe.
