Since one of our primary goals as victims of N, to have NC with them ever, I don't know if anyone will be able to answer this question or provide any anecdotes.
I am wondering what becomes of N's/what ends, consequences they meet/experience as a result of their mistreatment of people, and women, in particular. Dr. Vaknin says that they wind up broken, alone, and/or destitute, but that's really vague because that can happen to anyone.
In my case, I was with a somatic N for 5 years who's probably ef'fed hundreds, if not, thousands of women around the world (his job took him abroad, or so he claimed) over the course of his 50+ years as a N. Nothing really bad ever seemed to happen to him. He was always "upbeat" and happy-go-lucky. Statistically, it seems impossible that he should have gotten away with murder for so long and not have to pay any kind of price. You would think a husband or boyfriend would've beaten the tar out of him by this point (I found out that my N targeted women who had significant others or children, so that way, they would be tied down so he wouldn't have to take care of them). I'm not sure if he's even ever had a STD as a result of his promiscuity.
