I think when we use "evil" or "demon" and such to refer to human beings, all we are saying is that we aren't capable of understanding them or helping them. If you're a "demon" then I don't have to feel bad as a professional for being unable to help you in any way. I don't have to feel bad for not relating to you as another human being, I'll put that blame squarely on you. It's a cop out.

Everyone I know that has a PD is exceptional in some way and most are extremely intelligent. Not every therapist/counselor/psychologist/psychiatrist was at the top of their class. Some of those people barely graduated. Some of those people couldn't pass the licensing exam the 2nd, 3rd time (true story, I know someone who failed 3 times.) I guess that would be the point where my narcissistic traits kicked in because my feeling is "Sorry you are so intimidated by me that you need to villanize me. Buh-bye." One of my exes who I was convinced either had NPD or Anti-social PD had this quote as her email signature and in some ways it is pretty true: "Great spirits have always encountered violent opposition from mediocre minds." -Albert Einstein
