Empathy literally means the capacity to recognize the emotions being experienced by another sentient being.
It is almost always bound up with sympathy and compassion. Empathy as we normally think of it is a good thing, a liberal thing, a Buddhist thing, a kindly thing. But is that a good thing?
William Blake wrote the wonderful book of poems Songs of Innocence and of Experience. When I first read Blake in my late teens, I adored the poems and illustrations of the Songs of Innocence and largely disliked or ignored the Songs of Experience. I liked the joy, innocence, and passion of the Songs of Innocence but not the sober truths of the Songs of Experience.
Culturally, as far as I can tell, America is infatuated with the innocence of empathy, but not the sober truths that should go hand in hand with it.
If all people were nice and kind and never did bad things, it would be good to be innocent about empathy. But not all people are good. Indeed, most of us are only good sometimes and some of us are really bad a lot of the time.
Do you have the capacity to recognize the emotions being experienced by a person intent on doing harm? Doesn’t our current sense of what empathy entails leave out empathy’s evil twin, the bad emotions and intentions of other sentient beings?
I don’t know if it is still true today, but Japanese tourists visiting the USA used to get mugged and raped at levels well above their percentage of the population. The reason was, and maybe still is, they were too innocent and could not perceive the evil intent of their new “friend” or the cool dude asking them for the time.
This happened because Japan has less violent crime than the USA and because Japanese tourists were not able to imagine or read American situational exchanges. And this shows that empathy for evil is based both on expectation and culture, which are close in nature.
The Buddha said that we can only really know another human being after long association. Even he cautioned about being innocent and empathizing only with the good we see in others while failing to recognize the bad.
