Hi everyone ! 
To be honest I am not sure if I should post here my question but I am 29 and have a sister who is now 34 and I always saw something odd in her. 
I realised few month ago that she almost had all the traits of a sociopath (or narcissistic pervert) : she always talk about herself (if you had a bad day, hers is worst, for instance), jealous about me (she disagree on that but all my family confirm), she has no empathy or showed altruism. She doesn't seem to have remorse for what she had done wrong.
But since 5 or 6 years she went to therapy and since then she always play the victim about everything. One single remark about something and she can go crazy. There is also something cold in her messages where she tries to play the victim by saying "I am disappointed or sad for this thing that you have done or said". 
She drove few ex mad. I saw two of them crying (and she said to us that they were violent).

I can give you dozen of examples but I was just wondering if someone can be sociopath and also very sensible regarding any kind of remark, behaviour or whatsoever (or is it just a play to be the victim)

Thanks in advance !
