Make a guess

[UchihasRightfulHeir]

Make a guess a to why sasuke has the rinnegan in only one eye.

Also, if its the juubi eye shouldnt it be red and not purple like madara's rinnegan.

 

[Rokudaime Hokage Naruto]

Madara's gona steal it then Naruto will defeat Madara while Sasuke watches.

 

[Zen Uchiha]

Naruto can't defeat Madara alone

 

[Melania]

I always assumed it was because the power he received was on his left hand.
