[ When Kakashi looks at Obito, he doesn't see someone without humanity. He sees too much of it. Humanity, in its ugliest, most tragic of forms. Obito is broken. And Kakashi can't think of any other way to fix him.

Obito is his responsibility.

And this is his penance for failing him. For failing Rin. For not being able to protect what mattered most. ]

This is something only I can do.

[ Not only as a shinobi of Konoha, or as a former member of Team Minato, but as a man who lives only because of Obito's sacrifice in the first place. ]
