This is so well-put!
I thought of our ancestors, the weak little monkeys who had to work together or die, had to understand each others' minds and hearts. Cooperation was a virtue, cheating was a profound crime.
I think they'd recognise these "no empathy!" individuals as the cheats they are.
Books are bottled empathy. They’re telepathy in physical form.
Fiction makes us better people because it gives us a safe place to experience and learn to care through the most complex pain.
Remember: fascists have designated empathy a sin & moral failing. They don’t want you caring for anyone.
