There was once a man with the heart of a sweet innocent child, but with the face of a raging demon. This is his story, his Angel Densetsu.
My exaggeration aside the manga does show Junior and his buddies in bandages, and we have no reason to assume any of those mooks had aura given Jaune didn't have it and they were wielding axes that had "weapon" written on them as opposed to any actual weapons. She at least HURT them. It was definitely unprovoked violence and that was my point.
