Do you agree with my theory on who danzo is from naruto shippuden?

Now I have a theory that everyone seems to have been over looked. Its worth pointing out ive watch all of the shippuden episodes some of the original naruto episodes and read very lil of the manga but i do know a good deal about danzo from research i did. Any way my theory is that danzo cant be obito since hes to old, I doubt hes tobi(AKA madara uchiha) altough i wouldnt be suprised if he was. But i suspect that he is madaras younger brother who he stole his eye from so that he would no longer be blind but what people over look is that for all we know he only stole one of his brothers eyes i mean honestly after he took the first one would his brother just sit there and let him take the second one? i believe that madara took one of his eyes and his other eye is still blind thats why he wears the the bandages on his left eye and danzo wheres his bandages on his right eye and thats his sharingan eye. I ume it was injured during the time madara tried to steal it his other eye is a regular one he stole from a random person.
