Whether it is predetermined at birth to lead a life of crime is a question that has been debated for decades . Nature versus nurture is a very controversial argument regarding what influences the behavior and personality attributes of individuals. Nature is entirely dependent on an individual's genetic combination which dictates their character and appearance. On the other hand, education depends on the environmental factors that an individual is exposed to and which ultimately shape their personality. Nature and nurture influence individuals to some extent because individuals are exposed to both in one way or another, dictating their developmental process. I will show that lack of childhood care and life events cause serial killers, but I will also show examples where serial killers are not the product of a bad experience and 'childhood.

Get an original essay The word “serial killer” or “serial murderer” means the killing of three or four victims over the course of days, weeks, months or even years with a “cooling down time” in between. The murders are usually unrelated and the victim is a complete stranger. The goal is psychological, to punish the victims. Typically, murderers are sexually deviant and act out their sexual fantasies with their victims. Many come from dysfunctional families and were ignored or abused as children. This is why they pray for vulnerable victims, including children, young women, prostitutes and adolescents. Nature theory states that behavioral traits are innate and present in human nature. Jeffery Dahmer, a notorious serial killer, believed to have been born with part of him missing, could be considered a possible explanation. Scientists supporting this theory say this unexplained behavior causes brain damage, particularly in the frontal lobe, or possibly other genetic disorders. Damage to areas such as the frontal lobe, hypothalamus, and limbic system can lead to excessive anger, loss of control, impaired decision-making, and abuse. According to Rutigliano, "the frontal lobe is considered responsible for much of the activity that makes healthy and adequate social relationships possible." Many scientists believe that this part of our brain is our moral compass, which would have dystopian effects without this vital guidance. Research conducted at four universities showed that people with frontal lobe damage had irregular social feelings and a lack of empathy. This is easily demonstrated by one of the world's most famous serial killers, Ted Bundy. He said: “I don’t feel guilty about anything. I feel sorry for the people who feel guilty. However, other scientists have suggested that if the limbic system is absent from inside the brain, it could lead to uncontrollable rage and hostility. This idea of ​​a theory of nature could provide possible explanations for the murder of 33 young men by John Wayne. At the age of six, John Wayne Gacy Jnr was knocked unconscious after being hit on the head by his father with a broomstick. Additionally, aged 11, Gacy was accidentally hit in the forehead by a swing and caused a blood clot on his brain (but this was not diagnosed until he was 16) and left him caused to pass out on numerous occasions, possibly made worse. by his cardiac arrhythmiacongenital. Scientists who support the natural theory believe it is possible that this severe head trauma was the cause of his abnormal and violent behavior. However, there is an opposing theory about education. This theory differs from others in that it focuses on the control exercised by the individual over external influences during socialization. These factors may include a person's family and the way in which their parents exerted an effect on the child that may have resulted in psychological harm, producing a person with different expectations and values ​​from the rest of society , namely that serial killers live without moral conscience. Serial killer Henry Lee Lucas lost an eye at the age of 10 after being infected following a fight with his brother. A friend later described him as a child who often attracted attention by displaying frightening and strange behavior. Lucas' mother, a prostitute, forced him to watch her with her clients and made him cross-dress in public to attract clients. This type of behavior could explain why Lucas sexually abused his victims before killing them, lacking a moral conscience and accepting this as the norm. Adults who were physically, sexually, and emotionally abused as children were three times more likely than non-abused adults to behave aggressively, as this abuse is a major factor that turns both men and women into serial killers. Anger emerges and culminates in a series of gruesome sexual murders and intense, violent proceedings. All of this is meant to repress years of helplessness and humiliation when the serial killer was younger. They grow up without idealization, where they struggle to develop an ego that is normally learned from their parents. However, many people believe that the actions of a serial killer are simply too shocking to be excused due to poor upbringing and cultural influences. be identified as a theory of nutrition. Such behavior is therefore considered to be caused by an abnormality or "evil gene", which led to violent murderous behavior. Ted Bundy's mother, interviewed for her in the Netflix series, reported that Ted acted much more bizarrely than his siblings. She reported seeing Ted run away at night before going into his teenage aunt's bedroom and hiding knives under her blankets. It is believed that chemical imbalances can cause violent behavior. Monoamine Oxidase A' also known as MAO-A. MAO-A is an enzyme which, in humans, is encoded by the MAOA gene. A link has been established between the MAO-A gene and antisocial behavior. It was found that “maltreated children carrying genes causing higher levels of MAO-A were less likely to develop antisocial behavior and aggression.” There are numerous studies that support this claim, both in animals and humans. A notable study is that of "Brunner in 1993", who carried out a famous study on the males of a large family from the Netherlands, whose members displayed high levels of aggression. Five of the men had the dysfunctional version of the MAOA gene. Females in the family were not affected by the genetic dysfunction. The MAOA gene is carried on the X chromosome, and since females have 2 x chromosomes even if they have the dysfunctional MAOA gene, their corresponding Another cultural argument is social learning theory. Social learning theory leads toTraits acquired through training or through rewards and punishments. This does not mean that serial killers learned to kill by watching others kill. Emphasis must therefore be placed on the concept of reward and punishment. Bandura's social learning theory argues that people's behavior today is directly due to past experiences and that learning occurs through personal interactions and the influence of others around them. Violent and offensive behavior is modeled using modeling. Children adopt these habits from their parents or from the objects they look at and perpetuate this path from generation to generation, creating a vicious cycle and a violent behavioral culture. Individuals can also be affected by social factors and learn from their peers. Serial killers also learn by modeling. Studies show that aggressive behaviors can be taught through media such as family, culture, and even social media. Children who grow up in homes with abusive parents tend to imitate these activities and the power of interactive media in shows, movies and video games can never be underestimated. Luka Magnotta's student Jun Lin's murder was his own reenactment of "Basic Instinct," a '90s thriller. Magnotta was clearly obsessed with the 1992 film "Basic Instinct." Detective Nick Curran is smitten with Catherine Tramell (played by Sharon Stone), a crime writer with a string of mysterious deaths behind her who depicts the murders in her fiction. In the film's initial murder scene, Tramell stabs Boz repeatedly with an ice pick, Magnotta kills Lin with a screwdriver that he modified to resemble an ice pick and titled the video he posted " 1 Lunatic 1 Ice Pick". DNA and biological ties to our parents Finally, not all serial killers grow up in unpleasant conditions. David Berkowitz is a serial killer commonly believed to be created primarily by nature. As a child and young man, everyone who knew him described Berkowitz as quiet and polite. His adoptive parents, Nathan and Pearl Berkowitz, raised David in a loving and supportive environment. David grew up in an environment conducive to good mental health and overall happiness. His upbringing could not have caused his later actions, so it is considered that it was something in his nature that caused these actions. Although there is no record of David's biological family's mental health issues or criminal history, it is assumed that biological factors contributed to his behavior. It is clear that the care he received from his adoptive parents could not have played a role in the killer he became. Berkowitz said the reason for his murder was to "silence the demons." He claimed that the demons in his head would never stop tormenting him; to get rid of them, he started doing what they wanted. Along with this, Berkowitz also said that when the dogs howled, he was convinced that these dogs were demons telling him to kill women. Another example of his mental disorders affecting his life came when he was an adult. He was convinced that the owners of his house were part of the demonic conspiracy. Berkowitz later moved into another apartment but still felt controlled by the demons in his mind. With this evidence, it is clear that David Berkowitz suffered from a profound psychological dysfunction, likely rooted in his genes. A syndrome that is in the nature of serial killers is XYY syndrome. A serial killer had an X chromosome.
