It’s an age old question: what influences a person’s
 character? Is it nature or nurture? In a new book released this
 week Helen Morrison, a forensic psychiatrist who has interviewed
 over 80 murderers, adds her own slant to the question.  We are a nation currently obsessed with serial killers. Every
 new drama programme seems to be an off-shoot of Cracker, Prime
 Suspect,or the like. The popularity of CSI is what made Channel 5
 respectable, so popular in fact that it spawned CSI Miami, and
 CSI New York. The latest film to depict the life and times of a
 serial killer, Monster, was a hit with critics and audience
 alike. With its detailing of the minds and behaviours of some of
 the world’s most horrifying serial killers, no doubt
 Morrison’s book will hit the bestseller lists.  So, what is this morbid fascination with complete inhumanity?
 There is something of the car crash phenomenon in it. We are
 compelled to watch something tragic, something out of the
 ordinary. We are drawn to view death, in all its gruesome forms.
 Perhaps it makes us feel more alive, more grateful for life.
 Someone stuck in the rut of mundanity can tell themselves that no
 matter how much life sucks, at least they haven’t been
 dismembered and buried under someone else’s porch. It’s
 a life affirming thing.  But even more compelling is the desire to make sense of
 something so completely senseless. How can members of our own
 race be capable of such evil acts? How is it that people,
 possibly people we know, can take actions which revolt against
 every moral, ethical, and emotional code that we follow?
 It’s like watching a freak show, a version of the circus
 displaying the Elephant man, the bearded lady, the Siamese twins
 joined at their skulls. They are like us but unlike us, part of
 the same species but seemingly a different strain of the race.
 Serial killers distinguish themselves by the horrific nature of
 their behaviour. Yet they still look like us.  While television shows mainly focus on the killing rather than
 the killer, films such as Monster invariably draw upon the
 killer’s history, their invariably extreme childhood abuse
 and severe mental anguish, in an attempt to begin to explain
 their actions. We don’t like things we can’t explain;
 they are more dangerous, less controllable and by that reasoning,
 less preventable. This is the appeal of the nurture argument. If
 it can all be put down to life circumstances, then maybe we can
 undo it, even catch it before it’s too late. If we take more
 care of our young people, our abandoned, rejected, neglected,
 then perhaps they won’t grow up to do obscene things. The
 argument against this, of course, is that while killers, without
 exception, have suffered abuse in their lives, only a very, very
 small minority of abused youngsters grow into killers. This is a
 point made by Morrison, who’s firmly on the side of Nature.
 She suffered serious abuse in foster homes as a child. If abuse
 was the link in serial killers “then why are not all abused
 children serial killers?” She writes, “I was physically
 abused. I am not a murderer.”  It’s certainly a good point. Perhaps while abuse is a
 necessary factor, it is not a sufficient one. Morrison believes
 that the cause is purely nature; that the killer’s addiction
 to killing stems from a genetic anomaly. More specifically, she
 contends that there is a fault in the hypothalamus – the
 section of the brain that regulates emotions and moods. She also
 draws attention to role played by chemicals in the body, such as
 oxytocin and vasopressin, which instigate emotions.  The idea that evil behaviour stems from nature, some kind of
 chemical imbalance, appeals because it sets such people apart
 from the rest of us. ‘They’re crazy’ we’re
 reassured; no one we know could possibly act like that. Watching
 the activities of serial killers on television is one thing.
 Thinking they might live next door to us is quite another.
 Thinking they might sleep next to us is inconceivable. Yet, as
 Morrison points out, most serial killers have families.  This, she explains, is precisely because of the very normality
 of it: “Most serial killers rarely abuse those very close to
 them because the very idea of a wife and kids is part of a
 structure that keeps them ‘normal’”. Nor do they
 look particularly crazy on the outside. The Yorkshire Ripper, for
 example, spent hours grooming himself and, like many others, was
 polite, even charming, on first meeting. It is scary to us that
 we may not be able to identify a resident evil residing close to
 us.  Morrison doesn’t know exactly what it is inside the brain
 that drives serial killers, but she believes that with the
 advances in medical testing we one day will. This is the reason
 that she keeps the brain of notorious killer John Wayne Gacy (who
 killed 33 young men and buried them under his house) in her
 basement, in the hope that it will prove useful in future medical
 research. Morrison likens serial killing to drug addiction. While
 interviewing the Ohio killer Michael Lee Lockhart (who murdered
 and eviscerated 20 women) she had a breakthrough of
 understanding.  She asked him about his first victim; what led him to kill for
 the very first time? He told her how he had got up late in the
 morning, and while in the shower: “It hit me. I had to go
 out and get me one.” “That was the one sentence that
 made everything gel,” according to Morrison. “In my
 psychiatric practice, I treat drug addicts. I know when they need
 their drug, they have to get it and nothing else exists. The
 drugs for people like Lockhart are the people they murder. They
 are addicted to killing.” Perhaps one day we will be able to
 identify a gene that drives people to compulsively kill. We will
 isolate and treat it. One can only hope. But we should not let
 our search for this make us overlook the less obscene, but more
 prevalent, abuses that continue unabated in our world.ARCHIVE: 2nd week TT 2004
