I recently found someone called Dr. Ramani on youtube, and she's not giving any scientific reference but I can resonate with her words soooo much, both for myself and for some of my past relationships.

One of her videos basically says that yes, narcissists do know that what they're doing is wrong and yes, they do kind of know that you probably don't like it; they just don't really care. They need their dose of admiration and they feel entitled to it
