So why would someone lack empathy?

Like if there is a 4 year old whose parents hit them - then they go to school and hit other kids. Is the 4 year old evil? Or were they taught that behavior?

I’m not saying that adults are 4 years old and aren’t responsible for their actions, I’m just saying that some people have VERY different opportunities than you and I have had.

People are complicated, but my (liberal) values are exactly what one would expect me to have if you look at my upbringing and education. If I had a different education and upbringing I almost certainly would have different values.

Not fun to admit, but true.

I prefer to call actions bad rather than people. People are pretty complicated, and it’s not a level playing field.
