Laws are not the only existing influences. Even if you mean to include other social constructs, those are still not the only extant influences. Based on my understanding, Genghis Khan was himself a lawful force…just not the same laws as other groups. I believe this followed the usual pattern of human history: in-group gets favourable laws, while out-groups get their own laws ignored whilst unfavourable laws are pressed upon them. Perhaps you meant the natural human capacity for violence? If so, it is a non-sequitur to suggest that only laws provide an evolutionary pressure against this.
