My favorite cousin told me she is a Sociopath; I am questioning my reality and feel like I can’t trust anyone

I called my cousin after several years since I went no contact with my family. We had a long discussion about our toxic relatives. She confirmed that she also saw that my mom is a sociopath and pedophile. We talked about our traumatic childhoods and she seemed supportive and empathetic.  But then she told me she was also a sociopath, had no empathy or remorse. I told her that was not the cousin I know and that she was loving and that she was probably gaslight/scapegoated to believe she was bad. Then she got mad at me and said, she couldn’t believe I didn’t understand people can trick others just like my mom did. She said she had to learn and copy others emotions. She told me about how she is in an abusive relationship with a rapist/narcissist but it works because she is crazier. She said she could kill someone and doesn’t care. She said the only reason she is not as bad as my mom is because she learned a moral compass from our grandma.

I feel so scared. She is the first person to really confirm that my mom was also a sociopath... but now I am scared of her. Can she really be a sociopath?? I mean she seems so Insightful... I feel this urgency to help her to get her out of her abusive situation but now I am thinking I should stay away?!? She wants me to reconnect with the family who scapegoated me to help others see the truth about how abusive my parents are. She said they were brainwashed by my parents that I was the bad one which is why they blamed me for the abusive and didn’t believe me. I told her I am done with codependency, I can’t save others, they can only save themselves, and I am done trying to convince people of my truth/abusive history. I told her I can compassion for them, but they do not have to be in my life.  But recently, I have been thinking of maybe reconnecting with some of the family who were not my direct abusers.

Probably not a good idea. It is also scary that my cousin told me she is a sociopath. The world is so scary... who can we really trust? Some people are so good at tricking..
