#Naruto ch576: looks like the Uchiha-Senjuu hatred hasn't dulled one bit over the ages. #manga 

So Itachi and Sasuke meet again against all odds, and I get to be
exposed to Sasuke's personality all over again.... the pain doesn't
dull over time. It really doesn't. I wonder if Itachi will be able
to make a dent in the iron core ways that Sasuke has been set in. If
he can't do it I don't see how Naruto can.

Madara seems just as damn bitter as the legends said. He's sh*tting
on the kages, especially the Hokage. And they don't seem to be able
to touch him. It's not looking good for them right now. They're the
kages. There's no cavalry for them.
