If you watch the crime TV shows, the Narcissist criminals always push too far and metaphorically try to steal more than they can carry. Like Lance Armstrong. They say if he had never returned to cycling that seventh time he could have kept his prize money and his endorsement contracts and rode off into the sunset. But someone dangled that one extra carrot and he just couldn't walk away. The same with the people who commit horrific crimes. They always marry some chump and believe that they should get his estate and then take life insurance policies out on the guy. Then kill him in an impossible way and tell authorities a story that no one could believe and by the time they realize how implausible it is, they have to keep telling it over and over and they end up going to prison forever. Like my mother. She fobbed the lie that her accomplice was saving her from being raped by the guy that ended up in prison.
