Sociopaths aren't always "bad guys". The scary, violent murderers you see on TV only represent the very low-funtcioning end of the spectrum. Chances are you've met many sociopaths in your life. They blend, and many times maintain some semblance of a normal life.
Educate yourself.

Yes, it's incredibly rare, but yes. The sociopath is almost always the dominate personality, the second or other personalities being almost like internal victims, forced to see what the sociopath does without being able to respond until the switch. At least for me, both personalities are aware of the multiple, however only the "normal" empath personality, the secondary one that only rarely surfaces, can remember the events that my sociopathic one experienced. It's hard to explain what it feels like, as the Lizzy I want to tell people, I want to get help to make the other one go away and just be Lizzy. I want to get locked up or die or anything to get rid of Rachel. But as soon as I go back to the sociopath (rachel) I hate myself for thinking that, I hate myself for trusting, for being weak, for wanting to give away the secrets. I can only remember what happened when I was Lizzy for a few hours after the switch back then it's gone until I switch again.
Vain narcissist and/or sociopath
Research believes yes and they are still looking for it.
yes they can, in my experience the child's narcissism is a result of being raised by a narcissist ,
The Defining characteristic of the narcissist is grandiosity. The narcissist is more likely to be attention seeking, envious and to desire admiration.The defining characteristic of the sociopath/psychopath is callousness. The sociopath/psychopath is more likely to engage in illegal activity, to be aggressive, impulsive and deceitful.
Sociopath.
The simplest answer is YES. He has ISSUES
Narcissistic Personality Disorder and Psychopathy can be -- and often are -- components of child abuse. They are both clinically-defined conditions with certain criteria that must be met in order for a diagnosis to be made.
There are technical differences, but it is largely a matter of degree. Neither is likely to ever be a decent partner.
I think they'd say it's not the best thing in the world, those can be tough people to live with.
Narcissism & Sociopathy are on the same spectrum ALL Sociopaths are also Narcissists NOT all Narcissists are Sociopaths, though. The spectrum only runs one way.
If you were involved with one and he/she is a chameleon and fools others (only for a short time usually) then worry about getting on with your own life and realizing that others can look after themselves. Sociopath/narcissist will hang themselves every time ... they just have to open their mouths!
My older sister is a sociopath.
