@!Volpe:
I just said that because in these kind of manga, the protagonist usually doesn't kill ther enemies. Like Luffy in One Piece.
But I liked what Sorachi did.
Luffy doesn't kill because his fighting style, and how people exist in One Piece capable of surviving the kinds of beatings that he dishes out, besides when he was fighting Lucci he knocked him to the ocean without any concern.
Naruto doesn't kill because he always pussies out even if the Ransengan liquifies the insides of his oponents, someone else finish them.
Ichigo doesn't kill because… I don't know, don't care, he flipflops on this.
Gon used to not kill, he now understands that sometimes is necesary.
