He's doing over love. He watched his best friend kill the love of his life right after giving up his life for said best friend with 'protect XYZ' as a death wish. He felt betrayed. He's still going overboard, but come on... Naruto is really over doing it. Naruto was always annoying with his nonsense, but those last few war chapters made me want to swear of naruto. I rolled my eyes so many time during that saying 'oh god... more bullshit...'Im not misunderstanding. you dont think its immature he is doing this ovet a girl?
