@jpaskaruk On the point of the assumption, I personally didn't assume your l were making a moral judgement, but rather using a term that had meaning for you.
However it was received in a different context overloaded with other meanings, and so sparked ire.
The use of the term is, I think what was initially objected to. Given that it might have implications to others beyond your intent, it might be worth reconsidering choice of term for more effective communication in a crucial conversation.

I don't think empathy is what they lack, though - I think they are living in a bubble of unreality and surrounded by yes people who do not make them listen to, for instance, the actually-knowledgeable scientists and tech workers who understand the world that they have the option to not need to live in.
A sociopath lacks empathy - if I have to armchair diagnose, I prefer to diagnose them with having distorted vision, rather than being fundamentally evil.
