None of these studies are neutral. All such studies fail to take into account the Doctrine of Original Sin and that all of us are capable of the most vilest of crimes. Brain deformity doesn't determine which of us is capable of and may become a serial killer. Every person is capable of that. The article also fails at acknowledging that how we think, repetitively, has been shown to change the structure of our brain.

Or in other words, a person can have the "abnormal" brain of a psychopath by thinking as a psychopath. The idea that ADHD can somehow be a precursor to psychopathy shows the outright denial of a Biblical starting point and support of the false evolutionary view of mankind and his mental processes. The most one could say is that certain brain injuries can change behavior. But that was never the issue.

My original question about psychopaths had to do with whether or not a psychopath was such because of his constant rejection of God or if not, how would his behavior change after salvation. Would his ability to have empathy change, or would he strive through prayer to "fake" empathy out of obedience to God. To assume that most or all behavior of psychopaths is due to their having a brain disorder is without evidence.
