People in agricultural societies, frequently encountering lots of people, are likely to suffer a lot more from being overly aggressive than people in hunter-gatherer societies. Rulers have also always been quick to eliminate those breaking laws or otherwise opposing the current rule, selecting for submissiveness.
On the other hand, submissiveness is surely selected against in rulers, who as noted in the posting leave more descendants than proles. So perhaps in a society in which the strong rule and the weak submit there is some evolutionarily stable distribution along a submissive/​aggressive spectrum, rather than favouring one or the other?
