Studies have found a link between damage to the brain’s frontal lobe and changes in the amygdala in criminal serial killers.…
Biology contributes to killers. As people in today 's society, we are constantly being bombarded with the crazy actions that mankind is capable of. We watch the news and hear about murders, or even read a book about a mysterious killer. As we go through these pieces of reality, one can 't help but be struck by the thought--what causes a person to act so violently? There have been many studies done to try and find an answer. For a crime such as serial killing, there are two thoughts. The first idea is that serial killing is caused by an abnormality in the frontal lobe of the brain. The second idea is that serial killers are bred by circumstance which means they have certain genes also known as the negative gene that makes them prone to becoming a killer.…
Nova Science Now: Are killers born or made? Peering inside the criminal mind, can scientists help when someone died? Mr. Jackson, who’s a biologist, says “some men carry DNA that’s more violent than others. This gene is called MOA gene, its nickname is the warrior gene, we all carry it some more than others. Your Amygdala telling the rest of your body that something is happening. People with MOA genes have less grey matter than others but it’s not enough to make them aggressive, DNA is only one piece of the puzzle.…
Men are genetically stronger and their hormonal differences lead them to commit more aggressive, violent crimes. Also, men tend to be less socialized and lack verbal skills. Because of this men tend to lean toward aggression to solve problems rather than talking to diffuse conflict (p 43.) This chapter also talks about age and that as a rule of thumb adolescents, at the age of 18, tend to commit more violent crimes than that of other ages because they are psychologically immature (p…
To understand why a serial killer commits their violent acts we must understand if their motive was developed by nurture or nature. Research has provided evidence leading to believe that a parental figure or childhood environment can have a large influence of a child’s development into a murder. Sociologists believe that socialization factors play a key role in a serial killers life. One’s environment as a child and adult as well as…
It may not come as a surprise to many that there exists a significant difference in the gender of perpetrators of violent crimes. For example, in tracking the perpetrators of homicide in the United States by gender and year, one can find that males outnumber females many times over, with over 15,000 more males than females committing homicide in the early 1990’s (Fox & Zawiz, 2004). While it seems concreted that males perpetrate more violent acts than females, the data still shows at least 1,000 females a year behind violence. The question that arises from these findings concerns the reason for such a large gap between genders, and what facilitates it. Two popular lenses than can be compared in examining the question lie in the studies of sociological and biological influences on men and women – more specifically what influences women to be so much less violent than men given the statistics. It is important to consider learning experiences, either through natural instincts or facilitated through social means, and the history of individuals among their families. One of the aforementioned lenses has a much larger impact on creating differences in violent dispositions amongst men and women, and there is a vast array of evidence from which to draw upon for support.…
Surely there must be something wrong with someone who is extremely violent, or hurts individuals in ways our society will not allow. There are few things more repellent to 'human nature' and morality than the concept of a serial killer. What is different about the brains of these individuals whom our society finds unforgivable and unredeemable predators? Society might find a biological reason for such atrocities more comfortable than the prospects of 'good and evil' or a mistake. This paper will catalogue and attempt to organize the current biological differences between our minds and that of a serial killer.…
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" (Wartik 23).…
People who have this gene mutation are at extremely high risk for violent crimes. What makes researcher believe that killers tend to have this gene is not because they kill, but because of how violent this gene can make a person. Although this gene plays a great factor on killers and their crimes. Physical and emotional abuse as a young child also plays in. Research from the Department of Justice shows that children who are exposed to violence, being a witness or victim are often affected with long-term physical, psychological, and emotional damage. Children exposed abuse like this are at a greater risk of engaging in criminal behavior later as an adult and continuing this type of abuse to their…
Naturalism and the environment have the ability to change the brain’s of many lives. “ Murderers from relatively benign backgrounds are more likely to have reduced activity in two key brain areas than murderers from home wracked by conflict, deprivation and abuse,”…
Biological theories pertaining to the biological explanations of crime have been around for centuries. One of the most recognized theorists is Cesare Lombroso, founder of the Italian school of Positivist Criminology. In his biological explanation of crime, he believed criminal behavior to be genetic and that certain individuals who commit crime, can be identified by certain physical abnormalities or defects. One example is that murders have cold, glassy blood shot eyes, long hair and thin lips. He insisted that criminals committed acts that were beyond their control.…
There are two schools of thought, one that serial killers are born with certain genes that create homicidal tendencies in them and second that they commit a series of murders because of a particular environment (abusive family, abandonment, etc.) they are exposed to as children. Both arguments have been proved and explained through research and have been supported by statistics. However, it is seen that neither of the two are individually able to answer why serial killers behave in the manner they do. A thorough review of the research, statistics and what experts have to say in this matter will show that it is a mix of genetic and environmental factors that influence a serial killer. It is true that children who are victims of violence and abuse may become violent as they grow up to become adults but this does not mean they will become serial killers. It is necessary here that one is born with a genetic disorder and is also brought up in an environment that triggers the person with a genetic disorder to commit mass murders. Serial killers do not usually develop from a healthy mind after being subjected to a series of environmental factors, but are rather born with a set of bio-psychological characteristics that make them vulnerable to engage in extreme violence and sadism only after…
Violence is a learned behavior. Human beings are not born violent. We learn violence through sports violence, violence at home, and violence in video games, movies, and in the media. The violence we learn can also be through arts of fighting or self protection. Just having a brother or sister influences a child’s level of aggression. An older sister or brother who is very aggressive increases a younger sibling’s chances of being aggressive too. A younger brother or sister that is very aggressive increases an older sibling’s level of aggression. All these things contribute to why children are so violent towards their siblings.…
Berry-Dee and Morris state that killers come from a long history of abuse and parental distortion (2008). According to the FBI (2008), recent research indicates that how an adult relates to society is dependent on the quality of attachment with their parents and caregivers, and the extent of violence they were exposed to as children. Their findings indicate that “a child’s adverse upbringing can increase the risk of problems with self-control” (2008), or that the killer was insane during the act of murder.…
Another factor pointing towards the idea that psychopathy is genetically determined was identified by in a study at University of Wisconsin, Madison. When dealing with the terrible notion that some people take pride in murdering others, one should expect some abnormality in the brain, the immediate source of psychopathic traits. Scans of the brain revealed that psychopathy in criminals was associated with reduced connectivity between the amygdala, a part of the brain that processes negative stimuli, and the ventromedial prefrontal cortex (vmPFC), a region in the front…
