Do you think those with personality disorders are born or made that way? (or both)

This includes a lot of people….borderlines, sociopaths, etc. (I am still learning about psychology and stuff, so please forgive me if I am naive.)

To my knowledge, many personality disorders like borderlines are not really that treatable by medication or therapy. It seems that the person is just not “wired” right and can lack basic emotions, like empathy for others. Some may seem to lack a “moral centre” and they can be manipulative. Many are not aware of their pathology and cause many problems for themselves and others.

That aside, are people like this born this way, or is there something in their childhood/infancy that may make them have this pathology? If you think it’s different for different disorders, feel free to explain?

Please correct me if I am wrong about anything. I’m still learning and I’m curious!
