Predestined Serial Killers :: Genetics Murder Genes Essays

Predestined Serial Killers serial killer: a person who commits a series of murders, often with no apparent motive and usually following a similar, characteristic pattern of behavior. (8) As participants in today's information obsessed society we are constantly being bombarded with the brutal actions that mankind is capable of. One watches the news and hears about a murder, or reads a book about a mysterious killer. The only time that the New York Daily News has ever outsold the New York Times was when the headline claimed the letters that proved the 'real' identity of Jack the Ripper. As you wade through these bits and pieces of reality, one can't help but be struck by the thought-- what causes a person to actively commit such horrendous acts? There have been many different studies done in hopes of finding an answer. For a crime such as serial killing there are two main schools of thought. The first idea is that serial killing is caused by an abnormality in the frontal lobe region of the brain. Another theory is that serial killers are bred by circumstance. However, I believe that with some analysis the evidence for both theories can serve to prove that serial k illers are genetically different. Thus demonstrating that serial killing can find its origins in genetics. A startling amount of criminals on death row have been clinically diagnosed with brain disorders. A recent study has demonstrated that 20 out of 31 confessed killers are diagnosed as mentally ill. Out of that 20, 64% have frontal lobe abnormalities. (1) A thorough study of the profiles of many serial killers shows that many of them had suffered sever head injuries (to the frontal lobe) when they were children. To discover why damage to the frontal lobe could be a cause of serial killing, one must look at the function of the frontal lobe of the brain. The frontal lobe is located in the most anterior part of the brain hemispheres. It is considered responsible for much of the behavior that makes possible stable and adequate social relations. Self-control, planning, judgment, the balance of individual versus social needs, and many other essential functions underlying effective social intercourse are mediated by the frontal structures of the brain.
