What amazes me more is that Madara knows who he is. Somehow, Madara survived VOTE fight with Hashirama long enough to be around to meet and know Obito (especially after his turn) yet not be openly involved in Konoha and die before now so Kabuto could resurrect him and yet not recognize any of the Kage's beyond the old fart.
A simple souvenir of someone's kill
And like the sea
I'm constantly changing from calm to ill
Madness fills my heart and soul as if the great divide could swallow me whole
oh, how I'm breaking down
