I think supa, that I would honestly be BORED if Naruto didn't fight. He's got good skill, and doesn't require the hax in power sasuke got. Naruto NEEDS to be apart of the battle.
Besides if he just sits there on the island, we don't get answers.....I wanna know what Itachi gave him to help against Sasuke, (or Madara), because Itachi was awesome at planning ahead......
also all naruto needs is Shikamaru to help. I believe Madara himself said that fighting against Shikamaru is a bad idea....if I remember that right.
So, no. It's Naruto(his manga)......he can do what he wants to save his friends (unselfish......).
NOT wanting to save your friends makes you selfish.....
Also, why would you ever agree with Danzo? He wasn't right about anything, and required the uchihax and first hokage dna to even be a threat as a ninja......
and I won't even get started on A......who needs to be shut down hard...
