The narcissist goes to a fair amount of effort to make themself look good to the world, because this works in the plan so that people won’t question the behaviour of the narcissist. I remember the case of the Intermediate school teacher who was sexually molesting young girls, she was getting her daughters to bring friends home after school for mummy to play with, and then one of the girls (4 in total) told her father, and he went around to see that school teacher and told her that if she ever went near his daughter again that he would report her. She may have lost her job if he had of reported her to the authorities, but her reputation of being a glowing figure in the community would have made it hard to convince her without concrete evidence.

The only cure is to walk away from the narcissist and get time to regrow your soul. To be born again and become a better person.
