I'm inclined to agree; one can attach labels to this person of "psychopath", "narcissist", etc, but in a lot of people with that label there isn't a physical problem that they were born with, but events in their lives (often early childhood as per the article) that changed something in their brains for the worst. I don't think they were a lost cause, but they would have needed intensive therapy to try and unfuck some of what they've gone through, and it would only have worked when they were much younger (neuroplasticity etc).
