Are Psychopaths Evil or Diseased?


The BBC News article “Psychopaths: Born Evil or With a Diseased Brain?” is very much related to the lecture we heard from Dr. Neumann of the University of Wisconsin. The article focuses on Brian Dugan, a serial rapist and murderer, which was studied by Dr. Kent Kiehl, a neuroscientist from the University of New Mexico. Dugan is a white, adult, male prisoner, just like the prisoners that Dr. Neumann works with. Dugan was convicted of many rapes and three murders, two of which were seven-year-old girls. Even after being convicted and sentenced to death, Dugan showed no regret for the crimes he had committed.

After research and testing, Dr. Kiehl realized that the reason he committed these crimes might be because of his lack of empathy. Dr. Neumann told us that psychopaths have reduced amygdala activation and we know that the amygdala is responsible for emotional processing. Scans of Dugan’s brain show that it “has very low levels of density in a system we call the para-limbic system.” The para-limbic system includes the amygdala and pre-frontal cortex. This is not different from the brain scans of many other psychopathic prisoners Dr. Kiehl did all over the country.

Dr. Kiehl wants people to understand that psychopathy is a mental disorder and that it should be treated as such in the legal system. Also, he is trying to come up with ways to treat children who show signs of psychopathy.  Dr. Neumann mentioned brain plasticity in his lecture and that it might be a way to treat and prevent this disorder, especially in children.  Dr. Kiehl is trying to design an intervention for children with these symptoms because these children usually react badly to the normal disciplines of bad behavior. According to Dr. Kiehl, “You could prevent those individuals like Brian from ever developing and escalating into the individual that he is today.”
