The Difference in Narcissist, Psychopath, or Sociopath

you always have to deal with a few Nut Jobs in a condo

I have definitely one owner who has had bizarre outbursts directed at me as president. She has told others she will have my head on a platter at our annual meeting and her lies towards me are incessant. The other one hates rules and has aligned herself with the nut job. I wanted to find out whether they were simply narcissistic or if they might be a psychopath or Sociopath.

I've decided, after viewing this video, that both of the later categories are dangerous and one of these owners falls into one of these categories. They get a perverse pleasure in breaking rules but don't think about consequences...they lie and malign those in authority with whom they disagree and one actually has used cruelty to gain empowerment in her quest for relevance.
