Oro is too much of a "?"
Naruto did kill that sand dude that was affected by AL's Jutsu.
But the blow was softened, when later they said that he would die anyway because of that. But doesn't change the fact he was alive at that point in time.
Somes might consider that Sakura also killed Sasori. She wasn't unconcious when she fought him. She was there, she helped.. Its a team effort. the Kill goes to the group Chiyo and Sakura.
Kakashi undoubtly killed someone before the manga started.
And he did kill HAKU! WHILE TEAM 7 Jounin!
Thats a fact that nulify the topic: "Team 7 does not kill people"
I don't see what is thie bloodthrist that run into some of the readers here.
Get over with no one will die for no reason.. Unless its a big thing like Oro killing Sandaime, it won't happen casually. Naruto will not kill anyone, he is the type that belive people can change, and try to change them if you ask for forgiveness he will let you go!!
