To tell the truth I can't remember too clearly. Naruto manga was 11 volumes in the time span of a night. All I remember were the main highlights but nothing of the small details. The anime is refreshing my memory quite a bit ^_^

But you're right, I'm highly doubtful that Naruto will kill anyone, which annoys quite a bit. And, including the characters you named, I can imagine Kiba and Shikamaru killing. Most of the other children, I'm not sure. There just hasn't been enough occassions where killing was needed.

Love the icon. Ore-sama deserve to be praised *snicker*
