To me, empathy is required to be a good stoic. Empathy helps guide ethical decision making. Just because we’re not overwhelmed by it and show it outwardly, doesn’t mean it doesn’t exist.

Similar, though less essential, with other emotions. Stoicism is not the eradication of feeling. That would be denying our basic humanity and contrary to stoic principles. Instead, it is the mastery of it. Keep logic in control. Think Spock.
