“What types of people commit homicide?” This question is asked by psychologists and regular people alike. Could gender play a role? Does the age of a person affect their tendency to kill? How does someone’s financial stability effect whether or not they are a murderer? These thought provoking questions could lead to the answers that people want, but there is a problem which is brought up by forensic psychiatrist Douglas Mosman. “People exhibit different kinds of behavior or thinking patterns that could possibly lead to a violent act…But the problem is that there are hundreds of individuals who display these same patterns, who don’t go on to act violent” (qtd. in Heits 77). Many factors can push an individual to kill. Abuse, mental illness, relationship problems, and more may result in cases of homicide. So, what makes murderers different from those with the same problems?

People may think that the mentally ill are mainly the perpetrators of homicidal acts. Although people with critical mental illnesses are twice as likely to be violent, the majority of those with said illnesses are not violent. Drug abuse, divorce, and lack of employment are more likely to result in violent crimes than mental illnesses (Heits 77). Conflict with others, depression, and living in isolation can result in higher crime rates in addition to the previously mentioned factors (“Urban” np). These factors may affect the chances of someone becoming a murderer; however, there is evidence that behavior as a child can dictate the likeliness of someone becoming a murderer. It is even possible that a child can become a murderer when they are still in their
The nurturing of individuals plays a role in the making of killers, as 94% of serial killers had experienced some form of abuse as children and 42% have suffered severe physical abuse (Australian Institute of Health and Welfare, 2010). A child abuse is a determining factor, in which supports the idea that serial killers and psychopath, are influenced significantly by nurture (Australian Institute of Health and Welfare, 2011). In most cases social, cultural and physiological determinants all play a role in influencing serial killers to grow into a mass murderer. It is important that physiological and social determinants can be identified, so they could be altered for the purpose of preventing the number of crime.
In 2012, there were an estimated 14,827 murders and non-negligent manslaughter crimes reported by all agencies in the United States according to the Uniform Crime Report at the Federal Bureau of Investigation. Murder and non-negligent manslaughter are defined “as the willful (nonnegligent) killing of one human being by another.” A 1.1 percent increase occurred from 2011 to 2012. But it should be noted, this is a 9.9 percent drop from the figure for 2008 and a 10.3 percent decrease from the number of murders recorded in 2003. Of the murders that occurred in 2012, it is estimated that 43.6 percent were reported in the south, 21.0 percent were from the Midwest, 21.0 percent were accounted from the west, and 14.2 percent were from the northeast of the United States. There were 4.7 murders for every 100,000 people in 2012. The murder rate went up 0.4 percent from 2011 to 2012. It went down in 2008 by 12.8 percent and dropped 16.9 percent from 2003. The majority of offenders were over the age of eighteen and they accounted for 9,096 of offenders in 2012. According to the Uniform Crime Report, the number of offenders who murdered in 2012 totaled 14,581. The majority of these offenders were male, totaling 9,425. Female offenders totaled 1,098, and 4,058 were unknown offenders. Black males topped the list as far as race was concerned with 5,531 committing murder. White males followed with 4,582 offenders. There were 4,228 classified as race unknown regarding offenders who murdered in 2012. The victim data reported was 9,917 male victims and 2,834 female victims. Of those victims, 11,549 were over the age of eighteen.
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.

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.
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.
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.
The stereotype that exists for individuals who commit serial murder is one that mainly includes males of a specific race. However, it is now known that white males are not the only individuals who commit serial murder. Men and women from all racial and ethnic backgrounds and socio-economic statuses have been found to be serial murderers. Although this information has been presented to society, the cultural schema of the white male serial killer is still prevalent. The assumptions that involve serial murderers often include two aspects, the serial murderer is male and the serial murder is a type of “lust murder”, often involving sexual crimes by a sadist (Keeney and Heide, 1995). Keeney and Heide (1994) define serial murder to be the premeditated murder of three or more victims committed over time, in separate incidents, in a civilian context, with the murder being chosen by the offender.

Serial killers have many frightening facets. The most frightening thing about them is that experts still do not know what makes a human become a serial killer. Many experts believe serial killers become what they are because they have a genetic disposition or brain abnormality while other experts believe that a serial killer is created by childhood abuse; and some other experts believe that it is a combination of both brain abnormalities and abusive childhood experiences that creates a serial killer. A murderer is considered a serial killer when they “murder three or more persons in at least three separate events with a “cooling off period” between kills” (Mitchell and Aamodt 40). When defining a serial killer, their background, genes, and brain are not mentioned; perhaps one day those aspects of the serial killer can be included.
It is evident that those with mental illnesses have an increased likelihood of committing crimes. It is important to note, however, that not all people with mental illnesses commit crimes or violent behavior so a cause is not evident. Substance abuse, a mental disorder, is also seen as a large risk in violent behavior (Silver 2006). Hiday (1995) asks the questions of the direction of this correlation. Does mental illness lead to violence or is it vice versa?
The association of mental illnesses with criminal activity is allocated to the observation that a not overwhelming, but noticeable percentage of people in jails or prisons have mental illnesses. Mental disorders that can become very severe if untreated or treated inadequately, like schizophrenia, can be found among individuals in the criminal justice system that have committed crimes ranging from a misdemeanors to felonies. Although individuals with schizophrenia could have committed non-violent crimes, the violent ones, such as disturbing the peace by yelling or appearing threatening, domestic abuse, and murder, could be due to several factors that show people with schizophrenia have a higher risk of aggressive behavior (National Alliance on Mental Illness [NAMI], 2008).
The stereotype that goes hand in hand with mental illness that though seems to have improved over the years is still pervasive. Teplin, Abram & McClelland (1994) state that people in general, believe that people with mental illness are more likely to commit violent crime with those without mental illness. In their study they seek to find evidence to that statement – to learn if having a mental illness increases the likeliness of violent crime and recidivism after release from prison. This author seeks to discover the same using similar data to learn if there is a connection between violent crime and mental illness.
To begin with, numerous reasons for why a child acts in the manner he exhibits and why he continues to exert such dangerous and even fatal schemes. Recent research shows that factors ranging from inherited personality traits to chemical imbalances and damages suffered in the womb can increase the odds that a child will become violent (Johnson 234). Experts argue that no one is predestined to a life of crime. They believe that influences such as repeated abuse, extreme neglect, poverty, media violence, and easy access to guns play the major role in molding children into criminals. The father of serial killer Jeffrey Dahmer wonders, "If potential for evil is in the blood that some of us pass on to our children" (Seifert 23).
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 notion of the mentally ill being more likely to commit crime is a topic that is highly controversial and sparks much debate. However, I do believe that it is evident that mental illness can cause irrational and sometimes dangerous behavior, which not only do I find threatening, but more so sad. In the case of Luke Batty’s murder by his biological father Greg Anderson, not only do I feel extreme sorrow towards the victim, but I also empathise with the perpetrator, due to the fact that mental illness is clearly mishandled and overlooked in our justice system.
