Yeah. That’s pretty much it. In our society aggression isn’t tolerated- it’s encouraged. It escalates with time because to beat a complete pacifist for a job or resources etc. you just have to be a little direct. To take that job from someone a little direct you have to be more aggressive and so on. We could rid our society of such things but then any other culture that fosters aggressive competition would have an edge. Look at Japanese business as an example. Competitive but not traditionally aggressive- but it gains aggressiveness through dealings with the West because it had to in order to compete.
