Psychopaths simply cannot understand the basic nature of human emotion. It’s totally and utterly meaningless to them.
Dr. Galperin says that psychopaths are “hardwired this way. There is something missing in their brain. They can’t feel fear, they can’t feel love or compassion. When they marry, it’s not for love, it’s because they feel it’s convenient for them or it will help them achieve a goal.”
If that doesn’t sound like the perfect quality in a partner, what is?
A simple way to tell whether or not a person displays this symptom is to ask them when they last felt genuinely happy or sad. If their face goes blank for an inordinate amount of time, you should hear alarm bells going off.
