Merry krisimasi from Uchiha Brothers

OKAY I AM CONFUSED.
JUST WHO IS THE MAN BEHIND THE MASK OF TOBI.
WE ALL BELIEVE IT WAS MADARA UCHIHA.
BUT THEN WE WERE PROVED WRONG.
THEN MY Marafiki AND I ASSUMED IT WAS MADARA UCHIHA.
BUT WE DIDN'T HAVE ENOUGH BACKGROUND INFORMATION TO SUPPORT THAT SO WE LEFT IT BEHIND.
BUT NOW I HAVE COME UP WITH ANOTHER ANSWER.
I BELIEVE IT IS OBITO UCHIHA, KAKASHI'S OLD FRIEND.
I BELIEVE IT IS OBITO BECAUSE IF wewe LOOK CLOSELY wewe CAN SEE HIS SHARINGAN TECHNIQUE IS SIMILAR TO KAKASHI'S. THEY BOTH HAVE THE POWER TO SEND THINGS TO OTHER DETENTIONS. EXCEPT TOBI'S IS zaidi POWERFUL. AND wewe CAN SEE TOBI ONLY HAS ONE EYE. WHERE DID THE OTHER ONE GO? HE GAVE IT AWAY.
BUT I STILL CANT EXPLAIN WHY HE WANTS TO DESTROY KONOHA. SO THAT STILL HAS ME STUCK. BUT ALL IN ALL I BELIEVE ITS OBITO UCHIHA.
SO maoni AND TELL ME WHAT wewe THINK. I WOULD upendo TO HEAR YOUR THEORIES
