J., the Stoics prioritized virtue, obviously. They are very explicit that the four cardinal virtues are (i) completely interdependent (you can’t get one without the others) and (ii) marked by an intrinsic moral component.

This means that courage in battle doesn’t count as courage — again, for a Stoic, not for Greeks or Romans in general — unless the battle is a just one. Your example doesn’t fall into that category.
