Re: Naruto 607
Odds are Obito initiated the attack on Konoha for no better reason that to gain control of the Kyuubi, as part of the overall plan with Madara, and just decided to destroy as much of his past as he could in the process. But, as said, it wasn't clearly stated other than his inner monologue that he "doesn't care about this world anymore" or whatever.
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
