Here in honey bees, aggression was genetically linked to better health. NPA theory finds that also in the sense that individuals with both traits are healthier in general.
It's hard to transpose this to human studies. In NPA theory (as in sports) we don't consider being aggressive as pejorative. The definition of aggressive is important as we don't mean mistreating innocent others, just more self-defensive and being proactive about dangers?
