A criminal is an individual who is convicted of a crime and depending upon its severity, faces appropriate consequences. A criminal can exhibit a range of different behaviours and personalities; however, what is common among all violent criminals is that they are extremely aggressive and impulsive. Also, violent criminals often suffer from mental disorders such as psychopathy and antisocial disorder. Before individuals are capable of committing a violent crime they must first acquire certain aggressive behaviours or antisocial personalities that facilitate criminal behaviour. For example violent homicides, committed by psychopathic killers who do not feel any remorse or guilt. For decades it was believed that individuals that commit crimes,
Additionally, violent criminal behaviour is inherent in parents of criminals (Lyons 2007). The twin study is a study of a group of identical twins, which had either both or a single parent with a criminal background or record (Kendler et al. 2014). Each identical twin within a pair were adopted and raised in different households since birth (Kendler et al. 2014). The study of twins allowed the researcher to distinguish which behaviours are the cause of nurture (upbringing) and what are the result of nature (genetic makeup) (Connolly & Beaver 2013; Lyons 2007). The sets of twins were assessed for similarities and differences among their behaviours (Kendler et al. 2014). The results revealed that despite the up bringing in separate households the twins possessed very similar behaviours and later followed their biological parents in obtaining a criminal record in adulthood (Kendler et al. 2014). This finding proves that criminal nature is hereditary and can be inherent through generations. Additionally a documentary, My Brother the Serial Killer, based on the serial killer Glen Rogers, supports the belief that criminal and aggressive behaviours is genetic and not caused by external environmental factors (Monaghan 2012). In this case the brother of Glen Rogers speaks out about the crimes and the arrest of his serial killer brother (Monaghan 2012). What is interesting to observe in this documentary that both Glen’s sister and brother did not display extreme violent nature like Glen had, although they were raised in same household. This behavioural difference can be understood by genetic variations or mutations that Glen possessed and his siblings did not. Overall, the twin study and Glen prove that our genes predispose our

Individuals' personalities and overall quality of living are significantly influenced by several interrelated sources ranging from one's upbringing and quality of relationships to their own feelings of self-esteem and worth. Though this may seem relatively easy and un-complex, countless people today are engaged in persistent antisocial, criminal behavior, and seem unable to find an alternative, legal, means of living. While many have tried to explain such behavior through various theories, the causes of criminal activity remain to be satisfactorily clarified. Essentially, antisocial criminal activity has two aspects to it. Antisocial behavior is that in which one shuns society and others, while criminal activity is the act of performing a deed that violates an established law of the community. Obviously, such actions have serious consequences, which can range from community service and a fine to prison time. Even though there are several reasons that one may become an antisocial criminal, two theories of personality that provide reasonable explanations of this phenomenon, each in their own way, are the psychoanalytic and phenomenological theories.
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
Nature vs. nurture has been one of the oldest and most debated topics among psychologists over the years. This concept discusses whether a child is born into this world with their developmental work cut out for them or if a child is a “blank slate” and their experiences are what shape them into who they are. Over the years and plenty of research, psychologists have all mostly come to agree that it’s a little bit of both. Children are both born with some genetic predispositions while other aspects of the child’s development are strongly influenced by their surrounding environment. This plays into the criminal justice system when discussing where criminal behavior stems from. Is a criminal’s anti-social behavior just part of their DNA or is it a result of their upbringing? The answer to this question is not definite. Looking at research a strong argument can be made that criminals developed their anti-social patterns through the atmosphere in which they were raise, not their DNA.
Trait theory views criminality as a product of abnormal biological or psychological traits. It is based on a mix between biological factors and environmental factors. Certain traits alone cannot determine criminality. We are born with certain traits and these traits along with certain environmental factors can cause criminality (Siegel, 2013). According to (Siegel, 2013), the study of sociobiology sparked interest in biological or genetic makeup as an explanation for crime and delinquency. The thought is that biological or genetic makeup controls human behavior, and if this is true, then it should also be responsible for determining whether a person chooses crime or conventional behavior. This theory is referred to as trait theory (Siegel, 2013). According to Siegel (2013), due to the fact that offenders are different, one cannot pinpoint causality to crime to just a single biological or psychological attribute. Trait theorist looks at personal traits like intelligence, personality, and chemical and genetic makeup; and environmental factors, such as family life, educational attainment, economic factors, and neighborhood conditions (Siegel, 2013). There are the Biosocial Trait theories an...
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.
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).
The major premise of this is that the development of the unconscious personality early in childhood influences behavior for the rest of a person’s life. Criminals have weak egos and damaged personalities. The main focus of this is mental illness. In regards to social learning theory, one’s criminal behavior is learned through human interactions. Learning theories help explain the role that peers, family, and education play in shaping criminal and conventional behaviors. If crime were a matter of personal traits alone, these elements of socialization would not play such an important a part in determining human behaviors. Mental illness is part of the major crime causation for trait theory. According to some estimates, as much as 50% of the U.S. prison population suffers from some form of mental
Within the past decade there has been a wide range of research and evidence available based on both sides of the nature or nurture debate. Along with further research that identifies a number of determinants that have some form of influence towards criminal behavior and activity. This researc...
It is a fact that criminals have a smaller brains than law abiding citizens. Often, offenders share particular physical traits such as, being young males, muscular, having lower than average IQ, and a impulsive personality. Serial offenders are usually hyperactive and difficult children If a person has a low IQ, it is proven to be directly related to their tendency to be commit impulse actions that provide an immediate payoff. For instance, a rape or a mugging would provide a criminal with an immediate payoff. It is proven that crime often runs in families. In fact, chronic criminals are proven to be three times more likely to have criminal children. However, despite this information, scientists have no basis to come to any conclusions with this data. Therefore, one must consider other possible factors that may create a criminal mind, to come to a reasonable decision as to how one is developed.
They also explore the myths about the connection between genetic factors and criminal behavior. The first myth they looked at was “Identifying the Role of Genetics in Criminal Behavior Implies That There Is a “Crime Gene.”” This myth is dismissed because of the unlikelihood that that a single gene is responsible for criminal behavior. The second myth they look at is “Attributing Crime to Genetic Factors is Deterministic.” This myth is also easily dismissed because of the fact that just because someone has a predisposition to a certain behavior doesn’t mean that the person will take on that behavior.
There are more contemporary biological theories that have since developed. However, most are still nearly impossible to prove true; for example, the genetic theory of crime in fraternal and identical twins. This study is supposed to provide evidence that those who are born with the same genetically heritable trait are more prone to crime than fraternal twins or siblings because of the ...
JOSEPH, J (2001), Is crime in the genes: A Critical review of Twins and Adoption Studies of Criminality and Antisocial Behaviour.
Criminality constitutes strategic mannerisms characterized by apathy to misery inflicted on others, egocentricity and depressed self-control. Habitual criminal behaviour seeks to satisfy the offender’s desires for material prestige, power or pleasurable feelings regardless to damage inflicted to victim or society. Such behaviors extend mistrust, fuel prejudice, and largely corrupt social cohesion. Biological, psychological and environmental attributes are thought to heavily influence antisocial and criminal behaviour. Numerous studies have proven that active emulation, genetic predispositions and psychosocial labeling are all complementary to development and expressions of criminal behaviour. There has historically been a myriad of theories that attempt to explain criminal behaviour through different perspectives, all which constitute intricate paradigms that play a role in expressio...
