Serial killers have captivated the attention of scientists from the first signs of their existence to modern day. Interested by these killers’ inhumane actions, researchers set out to determine the cause of such graphic, horrific crimes. The brain has been brought into question regarding the motivation of these cold blooded killers. After extensive research, abnormalities of both the chemical composition and material makeup have been identified within the brains of numerous serial killers. These differences are more than mere coincidence, they are evidence that killers do not think in the same way. The killers’ drives and motives are irregular, just as their brains are. Not only are these variations interesting, but they are also crucial to the justice system in regards to the punishment of past, future, and present sequential murderers. It is important that as a society we learn the differences in the mind of a killer, and also recognize and understand them. A serial killer’s brain greatly differs in function from the average citizen’s brain due to physical variations in the brain and a different chemical makeup. The brain is arguably the most complex part of a human being and is linked to motivations, feelings, and actions. Therefore, when actions of individuals differ from “normal” actions, the brain is brought into question. Repeat killers commit actions that are not “normal” when compared to the general public and therefore research on their brains has been conducted. When comparing scans of everyday citizens’ brains as opposed to the brain of a convicted serial killer, the differences are clear. The two scans differ widely with the prefrontal gray matter of the average person’s, dwarfing that of the murderer’s (Adams).

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.
...theorize that serial killers have brain damage or other biological abnormalities that contribute to their actions. Damage to areas like the frontal lobe, the hypothalamus and the limbic system can contribute to extreme aggression, loss of control, loss of judgment and violence. Henry Lee Lucas, who was convicted of 11 murders, was shown to have extreme brain damage in these areas, probably the result of childhood abuse, malnutrition and alcoholism. Arthur Shawcross, another 11-time serial killer, was found to have had several brain injuries, including two skull fractures. While in prison, he suffered from headaches and often blacked out. Bobby Joe Long, convicted of nine murders, stated at one point, "After I'm dead, they're going to open up my head and find that just like we've been saying a part of my brain is black and dry and dead" [source: Scott].

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.
Several serial killers have a definitive and common personality profile. Almost every major social, biological, psychological behavioural influence that has been seriously suggested as playing a role in causing crime has been thoroughly thought as potentially contributing to the behavior of serial killers (Levin, 2008). The time period and amount of killings fluctuate depending on the individual committing the crimes. Usually, the murders happen in different geographical areas. A mass murder has a separate definition than a serial killer, because a serial killer has a “cooling off” period, where mass murders kill several individual in a single event.

Serial killers have long eluded law enforcement while simultaneously grabbing the attention of the public, and now more than ever, criminal psychologists are beginning to understand what makes a serial killer. In his true-crime documentary, In Cold Blood, Truman Capote depicts the horrifying murders of four members of the Clutter family and the search to find the criminals responsible for the deaths. Eventually, two killers are caught, one being Perry Smith, a detached and emotionless man. And although his carnage of the Clutters labeled him a mass murderer, many of Perry’s personality traits are characteristic of a serial killer. In fact, if detectives had not caught him, Perry could have easily become a serial killer.

As years go on so will the research on serial killers and hopefully we as a society will fully understand them and one day be able to cure whatever inside that makes them have the urge to kill.

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.
We can all agree that serial killers are unpredictable scary people but when it comes to why they kill, everyone has a different view. In my research paper I will get into the mind of a serial killer and try to figure out what exactly sets them into uncontrollable rage.

Mass Murderers and Serial Killers are nothing new to today’s society. These vicious killers are all violent, brutal monsters and have an abnormal urge to kill. What gives people these urges to kill? What motivates them to keep killing? Do these killers get satisfaction from killing? Is there a difference between mass murderers and serial killers or are they the same. How do they choose their victims and what are some of their characteristics? These questions and many more are reasons why I was eager to write my paper on mass murderers and serial killers. However, the most interesting and sought after questions are the ones that have always been controversial. One example is; what goes on inside the mind of a killer? In this paper I will try to develop a better understanding of these driven killers and their motives.
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.
Nearly 2,743 serial killers have been produced by the United States alone; a whopping 67.4% of the globe’s serial killers on record. Homicide is unfortunately not something that is terribly unfamiliar to humans. For thousands of years people have taken the lives of others. More often than not the people committing these acts believe that they are justified in doing so. Whether it be because of war or some realization of justice, they believe that they are vindicated. Some individuals, however, do not believe or even care if they are justified in their killings or not. They simply do it because they want to. These individuals, while all detestable, are not all equal. A strikingly cold-blooded character by the name of Albert Fish stands out from the rest for his especially loathsome motivations.
