True. I think there’s evidence in both directions. I feel personally though that in a healthy family, with strong boundaries, a sociopath or psychopath would be recognized and removed, or perhaps taught to mask to the extent of fitting in to society and likely never progressing to deeply harmful behavior. Our society in real life is itself repressive and toxic, many of not most parents are abusive in some ways, the birth process alone is horrific for mother and child even in the best of circumstances, so it’s not as though we’ve had the opportunity to study these individuals in a healthy society to see what their brains might do.
