A popular belief is that an abusive childhoods and other psychological factors influence the fate of a serial killer. Actually, most infamous serial killers are known to have abusive pasts. The environment in which a person grows up in plays a huge part in the molding of a serial killer. When children are abused at a young age, their abusers are practically “teaching” them to become cruel monster with no guilt for their actions. These children lack empathy because it was never shown to them. Being exposed to extreme violence or neglect, can cause a person to kill. Experiencing child abuse, whether it be emotional or physical, contributes to the way serial killer develops the way they do. The abuse usually comes from a parent, a school bully …show more content…
James and others have found that the orbital cortex in the brains of serial killers are a lot less active than the amygdala while processing information.(Hagerty). The orbital cortex is responsible for moral decision making, ethical behavior and executive decisions and the amygdala is responsible for fear, anger, violence, and appetites.(Hagerty). When the orbital cortex is not not as active as the amygdala, the person is more likely to be violent and less likely to make good decisions (Hagerty). James Fallon also found there is one significant gene associated with serial killers; the MAO-A gene, also known as the warrior gene. Serial killers are known to have a variant of this gene making them predisposed to violence. (Ashley) Serial killers are known to have a chemical imbalance in their brain when they are born, specifically the imbalance of serotonin. Serotonin contributes to the behavior of a person, low serotonin levels can cause anger, aggression, anxiety and depression (White). Many serial killer are born with a serotonin buoyant fetal development which makes them insensitive to serotonin and contributes to abnormal responses (white).They respond with much more aggressions and violence (White). A study by Newman el al. reveals that the nervous system of an average person differs from the nervous system of a serial killer. An experiment was conducted that shows that kills seek more …show more content…
Not at all. Brains and genetics don’t determine behavior – but they do set the stage. The real culprit turns out to be childhood
The question of whether or not man is predetermined at birth to lead a life of crime is a question that has been debated for decades. Are serial killers born with the lust for murder, or are their desires developed through years of abuse and torment? Many believe it is impossible for an innocent child to be born with the capability to commit a horrible act such as murder. But at the same time, how could we have corrupted society so much as to turn an innocent child into a homicidal maniac? Forensic psychologists have picked apart the minds of serial killers to find an answer as to what forces them to commit such perverse acts. Their ultimate goal is to learn how to catch a serial killer before he commits his first crime.
Hickey (1997), in his trauma control model of the serial killer, argues that various factors can contribute to criminality and in particular to serial homicide. These factors can be biological, developmental, demographic or familial, including childhood trauma (Hickey, 1997, as cited in Miller, 2014, p17). Hickey’s model includes 8 elements – Predispositional factors, Traumatic events, Low self-esteem and fantasies, Increasingly violent fantasies, Trauma reinforces, Facilitators, Dissociation and Homicidal behaviour (Hickey, 2016, p149).
The case of whether serial killers are born with the lust to kill or if they are truly victims of their environment has been a hot debated question by both psychologists and the FBI today. A serial killer is traditionally defined as one that kills 3 or more people at different times with “cooling off” periods in between kills. Both psychological abuse as a child and psychological disorders are to blame for the making of a killer. The nature vs. nurture debate is best applied to the mysterious behaviors and cases of serial killers and their upbringing and environment. Nature is the genetic and biological connections a person has, personality traits, and how genetic make-up all relates to a killer. Nurture is examining the upbringing and environment that a person is around that affects what a person becomes. In some cases however, the effects of only upbringing or only biological problems were the reasons certain serial killers committed crimes. Although there is no definitive answer to what plays the bigger role: nature or nurture, they both are contributing factors that make a serial killer. These deviants of society are afflicted with problems in either their upbringing or have psychological disorders, and are able to blend into our everyday lives with no apparent differences, yet they wreck havoc through their unremorseful killings.
In a Google search of “serial killer memorabilia”, approximately 135,000 results would appear. While the U.S. produces over eighty-five percent of the world’s serial killers (“Why do Americans Idolize Serial Killers?” 11), Americans still tend to treat these murderers as icons and celebrities. As defined by the Federal Bureau of Investigation, a serial killer is expressed as the unlawful killing of two or more victims by the same offender(s), in separate events. While it is no secret that serial killers have a different mindset than that of a normal person, do these murderers have genetically different minds? Although there is no exact answer as to what causes certain people to have the urge to kill, studies from the “Minnesota Study of Twins
Some psychologist believe that if a serial killer displays or kills his victims in such a way then it qualifies as fulfilling as sexual desire. These killers are usually diagnosed with a mental disorder referred to as sexual sadism. Psychologists refer to serial killers who kill in this manner as sexual sadist. A sexual sadist enjoys the ‘suffering or embarrassment of others to the point of arousal’ (Serial Killers and Sexual Sadism). Sociologists believe that a serial killer needs to “fulfil a sexual desire by turning a fantasy into a controllable reality” (Serial Killers: Nature vs. Nurture). Sadist crave the dominance and control over their victims because they feel as if they cannot control other aspects of their life. Another biological factor derives within the DNA of the person. Many killers have the “MAO-A gene (monoamine oxidase A). This gene, which has been the target of considerable research, is also known as the "warrior gene" because it regulates serotonin in the brain. Serotonin affects your mood — think Prozac — and many scientists believe that if you have a certain version of the warrior gene, your brain won't respond to the calming effects of serotonin (A Neuroscientist Uncovers a Dark Secret).” With this gene psychologist and scientist alike believe that this can foretell a serial killer before he becomes a serial
Krafft-Ebing (1886) found that the serial killer had been through cruelty of animal; enjoy the torture and the pain of their victim during his or her childhood period. Moreover, the mothers of these serial killers were most of time working or doing other things and usually the father were absent. These children experience rejection and lack of attention, therefore, this child grows up having low self-esteem. Research show that adults that gone through abuse and violent behavior during their childhood were three times more likely to become violent as adult more than the non abused adults (Dutton & Hart, 1992).
There have been many theories over the years about how a person becomes a serial killer, and how does having an unstable childhood effect a person. It has been proven by psychologist and stated by serial killers that their childhood is one of the many problems they faced that led them to become a serial killer. The childhood of a typical young boy would consist of loving parents, a stable home and having friends. As for serial killers this is not typical at all. During the childhood of a serial killer it is not uncommon that he or she was abused, raped, or even attempted suicide along with many other harmful acts that a child should not be faced with. There have been many studies on the childhood of serial killers, and how they grew up compared to other young children. Some of the traits most male serial killers have as a child would include killing animals, auto-erotic activities, physical head injuries, and even bed wetting.
Serial killers are defined to “be driven by instinct and desire to kill.” In a study done in 2000, Dr, Richard Davidson says, “people with a large amount of aggression – in particular people who have committed aggressive murders or have a social disorder – have almost no brain activity in the orbital frontal cortex or the anterior cingulated cortex while activity in the amyglade continued perfectly. The orbital frontal cortex and the anterior congulated cortex control emotional impulses while the amyglade controls reactions to fear.” Davidson concludes his research claiming that although environment can and will affect a serial killer’s thoughts, it is a killer’s genetic makeup that inevitably creates murderous thoughts.
It is also crucial to consider the genetic makeup of these killers when trying to decipher their motives. New research shows a potential link between a strand of genes and aggression and violence (Bradley-Hagerty). The MAO-A gene or (monoamine oxidase A) has been researched extensively. The gene is often referred to as the “warrior gene” (Bradley-Hagerty). The function of this gene is to regulate serotonin in the brain. However, there are different variations of the gene, one of which is believed to prevent the brain from feeling the relaxing effects of the serotonin (Bradley- Hagerty). Without these calming effects, the person with this version of the gene is genetically predisposed to fits of rage; fits of rage that could potentially lead to murder over and over again.
Many studies suggest that there are significant differences in the brain between individuals who possess antisocial personality disorder (psychopathy). While not all people who possess an antisocial personality disorder will become serial killers, every serial killer studied has an antisocial personality disorder; “Neuropsychological testing revealed abnormalities in all subjects tested” (Blake, Pincus, and Buckner 1642). Brain injury, brain abnormalities, or mental illness affects all the serial killers tested. Even if all serial killers had some type of abnormality in the brain, would that mean that they were doomed to become a serial killer? According to the experimental findings discussed in Neurologic Abnormalities in Murderers; 64.5% of serial killers have a frontal lobe dysfunction and 29% have temporal lobe abnormalities. The frontal lobes of the brain “control the essence of our human...
The question of whether or not man is predetermined at birth to lead a life of crime is a question that has been debated for decades. Serial killers are made not born; it has been demonstrated that a man 's initial years are the most vital years. A youngster 's initial couple of years is a period of experimentation, a period to make sense of things for themselves, a period to set up the bits of the riddle. Like a newborn child, the mental health is reliant on its environment. A youthful youngster 's mind resembles a wipe; it gathers data through perception. The surroundings of a serial killer as a little child can enormously impact the way he or she will go about his or her life and his or her style of murdering. Certain experience, for example, youngster misuse, divorce, liquor misuse, tyke disregard, as well as medication misuse, can be negative to the advancement of a little child. Numerous serial killers were illegitimate kids. Due to their childhood and early backgrounds, serial killers swing to crazy murdering frenzies.
There have been many serial killer cases that have attracted the attention of not only the media but of mental health experts as well. Many experts from a variety of different fields have come together to answer one question: Why did they do it? It is believed that most, if not all, serial killers have a mental illness, motives, and/or trauma during their lives that made them start killing. Serial killers are not only the effect of nurture but also nature. The environment of their country, the United States is our focus, can cause the number of serial killers to increase especially if the country itself is unstable.
The brain is the most complex organ in the human body. Since the beginning of time, scientists and neuropsychologists alike have studies its composition and how it influences human behavior. However, no human behavior has baffled researchers more than serial murder. Serial killers are dangerous animals that act upon bizarre influences that have fascinated the human race for thousands of years. Many wonder what could cause a person to take the life of another innocent soul. Do internal factors cause them to do it? Is it their environment? What causes a serial killer to kill?
Nature versus nurture has been argued in attempt to understand how criminals behave. The theory of what influences psychopath and serial killers’ violent and destructive pathways has not been agreed on till this day. Criminals such as psychopaths and serial killers have been researched for the past two decades. Scientists have found that genetics is a determining factor of who becomes a serial killer. It is important to understand the determinants involved within a serial killer, because if these social and environmental causes are discovered, they can be altered and controlled to reduce crime (Lykken, 1993). With more studies, we would therefore prevent mass murders and could assist in significant reductions of crime within society.
So what makes a serial killer? Levin points out that contrary to popular belief, serial killers don't just 'snap'; or 'go crazy'; (Douglas, p. 137). Many of the serial killers have been the victims of childhood abuse. Jack Levin stated 'Research shows many serial killers suffered abuse, incest or neglect as children and develop poor self images'; (Douglas, p. 137). Serial killers often have a childhood marked by the absence of any nurturing relationship. 'They often come from families where the parents were absent or ineffective, where authority was not defined, and where they could engage in destructive behavior undeterred-violent play, cruelty to animals, and incidents of arson being some of the childhood behavior patterns noted among many serial killers'; (Clark, p. 206).
