There are what is called "diabolical narcissists". Ann Barnhardt did a 3 hour video on this topic which is excellent. So, what are dn's? They are people who are evil and who cannot love. They do the work of their father, Satan, who hates all humans. Therefore, we can expect that these people do evil deeds without conscience bothering them, they justify all the evil they do and never feel remorse, never ask forgiveness and are unable to have a loving relationship with anyone. If you have one for a relative, as I do, you can look back on your relationship and see nothing good or life affirming, just pain. I recently contacted my dn relative after years of avoidance, to ask for thing this person had taken from my house. the answer: "That door is closed. I will never be reopened." That's the kind of cold certainty they possess. Just know that this person asked for the things to duplicate them and I assumed I would then get them back. How silly of me!! If you have the misfortune to marry a DN, you will never get love from them, ever. Even if they say it, it is not true. The title for the video on YT is " Remember Lot's Wife: Diabolical Narcissism."
