Do you feel narcissistic people are born with the predisposition to be that way…….

I have two narcissists in my family, my mom and her sibling. Both had zero discipline growing up. She even said so herself. They could say or do anything, with no consequences. It set up an environment for destruction as they became adults. They are mean, loud, abrasive, selfish, and obnoxious. EVERYTHING is about them, 24/7, and if it's not, there's hell. It was a nightmare growing up. The things they have both said and done are plain evil. They are not kidding in any way when they say cut ties with a narcissist. They will ruin your LIFE. 😧 I absolutely believe environment /upbringing is a huge factor.
