That never admitting to reality is a real hard one to heal from.

Dealing with narcissists or borderlines, you never get a straight answer. It is all gaslighting. Even on their death bed, or yours. You will never get closure.

That said, most people aren't evil geniuses. They are just following the script stuck in their heads. And never think on it. No self reflection. Especially in these areas.
