It's perfectly fine, showing empathy towards people who does not, is an increadible strength.
Depending on the situation, it could even change their views.
However, someone who tries to argue that empathy is bad, a weakness, does deserve to get a taste of what true lack of empathy is.
If I saw Trump or Vance alone on in a forest with a broken bone in the middle of winter, would I help? Yes, but i would be a huge dick about it once I realized who they were.
