For me personally I don’t have much control over my empathy. Sure I can look at someone and glean their emotional state based on conscious guessing, but my “affective empathy” as you put it, is more my brain subconsciously picking up on their emotional state and then sharing it.

For most emotions, including anger, it’s not targeted. Not until I actively participate in the emotion. It’s also not something that applies to everyone and every situation, with my own personal emotions easily overriding the empathetic emotions.

Of course, everyone experiences empathy their own way.
