I’ve often wondered this myself. Unfortunately there is very little Catholic literature on the subject I have found (this is pretty interesting). Maybe because it seems to be more prevalent in our modern times than in the past? Perhaps due to the lack of true masses? I’ve talked to a priest about it but he clearly had no experience with a true narcissist because he labeled it as simple selfishness and that I should pray to her guardian angel. Not bad advice, but it’s more than simple selfishness. These people can be and often are completely evil. Almost as if they have no conscience at all.

The narcissists that I have known all suffered through parental emotional neglect and/or severe trauma as children. I believe it stems from that. Unlike in a proper upbringing, they only had themselves for validation and comfort.

In our times, mother is out of the home and father is not leading the home. Children suffer greatly and some come out with NPD. They become insecure beasts trying to incessantly fill their ego with no regard for anyone else. Truly malignant. Sorry to anyone who has dealt/is dealing with one.
