IndexSerial killers are born evilSerial killers are not born evilConclusionA serial killer is a person who has killed 3 or more people in the space of a month, with a significant period of time between them. Serial killers kill out of desire and pleasure, their sexual desires and need to satisfy their exciting fantasies leads them to murder, but are they born with this desire or is it caused by bad upbringing? 96% of those that serial killers kill are complete strangers, meaning they have done nothing to harm or upset the serial killer, making him even more cruel as the individual is innocent, but also devoid of reason, the killers they often kill with motives such as revenge, but serial killers do so purely out of lust and desire. Serial killers are a rare breed as only 1% of murders are serial killers. There are some factors that can push a person to become a serial killer, medical examiners believe that becoming a serial killer boils down to three things: childhood abuse as it creates enormous anger, while neurological and psychiatric diseases of the brain can damage the ability to stop leads to violence. We can divide them into two main factors: their nature at the time of birth, which includes the presence of a mental illness, and brain damage if you were born with them or if they occurred in an accident. The other factor is their upbringing/culture, this examines the impact that external factors have, in socialisation, on that particular individual. These factors could involve the serial killers' family and how their parents raised the child, which could have resulted in psychological damage and consequently created a person with values ​​and normality different from everyone else in society. But which of the two plays the more important role: their nature or their culture? Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an Original Essay Serial Killers are Born Evil First, I will talk about the nature, genetic makeup, and why this has such a great impact on a person. For example Arthur J. Shawcross had a lesion on the MRI, he had an abnormality in the EEG, which could cause bizarre behavior, which happened because he committed 11 murders, his medical examiners even said that if he had not had brain damage he would not have became a serial killer (interview with a serial killer), this means that nature was most likely the cause why he became a serial killer, creating an argument in favor of the emergence of "evil" serial killers. Another example is Jeffrey Dahmer, one of the most notorious serial killers and suffering from borderline personality disorder. People with this disorder have poor emotional regulation and cause small things to cause excessively large reactions, so Jeffrey Dahmer is very likely to have an aggressive response to something small that his victims have done. This in turn increases the strength of this argument. John Wayne was a serial killer who killed 33 males, he was said to be a perfectly normal boy, polite and very kind, he had friends and showed no signs of serial killer instinct. At the age of 15 he suffered a blow to the head which caused a blood clot in his brain, which was only discovered at the age of 16 and he often suffered blackouts caused by the clot. Many scientists who believe that serial killers become what they are by nature, believe that Wayne's aggressive behavior was caused by the blood clot in his brain, this further proves that serial killers are highly affected by brain disorders, because if John WayneHad he not suffered from a brain clot he would not have had aggressive tendencies and loss of consciousness. Another example of a serial killer is Kohlhepp - he killed 7 citizens; A forensic psychologist, Kohlhepp says, had problems from the age of 15 months. He has shown strange and aggressive behavior since kindergarten, hitting other children and destroying their projects. He shot a dog with a BB gun and used bleach to kill a goldfish, there was no information that he ever had a difficult upbringing that would lead us to think he was born with his anger and pleasure in hurting others others. 84% of serial killers are men, this therefore means that if you are born a woman the chances of becoming a serial killer are much lower, leading us to believe that nature has a great impact. However, I could name an endless list of serial killers with mental illnesses and brain damage, but I could also name an endless list of people with mental illnesses or brain damage who are not serial killers or murderers, making us wonder what the most important factor is. really: brain abnormalities or bad education. Serial killers are not born evil. The most common trigger for serial killers that we know of is any form of childhood abuse. Arthur J. Shawcross claimed that he was sexually abused as a child by his mother, that she performed oral sex on him, and that the two had intercourse when Shawcross was 14, right before he ran away (interview with a serial killer) , which makes it seem like his childhood could have had an impact on him by triggering his mental illness. A further example, Jeffrey Dahmer, was said to be a perfectly normal child with no signs of abnormal behavior, until his family started moving around a lot, and that's when he started torturing animals, this shows that he had had problems with socialization and settling in a home could have made him have this desire to hurt others. Willy Pickton is a Canadian serial killer who is estimated to have killed 49 women in Vancouver, he was a pig butcher on his parents' farm and was said to have displayed a strange sense of humor ever since, he would cut the skin off the pig's penis, then he used them as a belt as a joke. He then continued to strangle his victims, then hang them in his barn and disembowel them as he did pigs, just as he did in his childhood, but he moved on from pigs to humans. Willy Pickton did not have any mental illness or brain damage which leads us to believe that his upbringing could have been the sole cause, his parents both died when he was relatively young causing trauma in his early life, and the fact that he treated his victims as well as the pigs he slaughtered show us that what he did in his early life could have led him to carry out these horrendous murders. Rosemary West is another famous serial killer who was convicted of 10 murders, she is said to have had a terrible upbringing which could be used as a motive for her gruesome murders. Rose's mother suffered from severe depression, which could have robbed Rosemary of any chance of a normal childhood. Rosemary became a teenager and did poorly in school due to her poor attendance, her parents were not bothered by this, making Rosemary feel even more unloved. Rosemary's parents divorced when she was a teenager. He lived with his mother for a while before moving in with his father when he was 16 in Bishops Cleeve. But her father was much worse because he was incredibly abusive and sexually abused her repeatedly. This could very well be linked to why Rose sexually abused his victims before killing them, lacking consciousness.
