I think it is even worse than that; becoming a surgeon destroys empathy.

That's interesting. I read a while back that psychopaths are not people who are completely devoid of empathy. Instead, they were defined as people who can control empathy. They can turn it on or off. They can turn it on when it suits them and turn it off when it would get in the way of achieving goals.

I doubt that. They may turn on and off the appearance of empathy. But real empathy* would not serve a psychopath too well.

I have an ex husband with some less than lovely personal traits. Genes being what they are, he passed a few on to our children. So I have long had a keen interest in understanding constructive uses for less than lovely traits.

My ex was a soldier who served his country for more than 2 decades and was honorably discharged. He is an honorable man. But he's not very warm-fuzzy.

* "Empathy has many different definitions that encompass a broad range of emotional states, including caring for other people and having a desire to help them..."

I would call those people borderline rather than full-blown psychopaths, but I'm not a psychologist.

Sounds like a lack of sympathy.
