thanks, Nanna!
Brutal, I'll try to give an example from my observation. When my sister (NT par excellence) enters a room where some people are gathered chatting, small talking, grabbing a bite and a drink together and just being happy (or pretending to be), even if she hardly knows those people, she'll turn to the person sitting next to her and show interest asking a couple simple questions like how's your mom doing, and bingo! she knows what that person needs to hear most at that moment. She conquers their hearts in seconds, wins their almost blind following her, without knowing how she did it. She just felt the other would be pleased no end if she offered them her old, barely-functioning stove. This is EMPATHY. Later she uses, abuses, misuses this person at will, ignores them when they need her most, betrays them, etc. As she told me, she's not interested in relationships of genuine caring with humans, only in "having the right contacts". This is [lack of] COMPASSION.
