lol, first off let me say you didn't own anything, you just said that tobirama's jutsu can't cut a person in half and I disagreed, you twist the manga to suit your arguments tho and I called you out on it, especially on kakashi and kakuzu. You claim that since kakashi got kicked and flew thru some trees that human flesh is tougher than wood, however that's not true, kishi only did that to demonstrate how powerful kakuzu's strikes were, not how durable kakashi is. if a genin tossed a kunai straight at kakashi's heart he would die, if he tossed it at a tree branch, it wouldn't even penetrate.
Tobirama's jet-stream sliced thru several branches that were thicker than most trees, and you claim it can't slice a person in half when we all know that wood is harder than flesh, I don't know why this is so hard to comprehend.
