Morality's Biological Nature

This essay aims to examine weather serial killers are born a certain way and their genetics define their psychotic tendencies or whether they're a product of a bad environment that they grew up. This essay looks at recent killings in the late 20th century as there is more information on the killers from this period and it's easier to gain details about their childhoods. Whilst I will look at various different killers to reach more rounded conclusions (see appendix for comparison table), this essay will focus on four in detail to examine the debate; Ted Bundy (1946-89), Jeffery Dahmer (1960-1994), John Wayne Gacy (1942-1994) and Gary Ridgway (1949-present).

What causes an individual to become a serial killer? Bio-psychologists believe that starting from birth the human mind is a “tabula rasa” or blank slate, and the individual learns behaviors and socio-cultural norms from individuals around them. This concept of nature versus nurture was based upon the idea that it is how you are brought up (nurture) that governs the psychologically significant aspects of child development and the concept of maturation applies only to the biological. The theory that explains the nature aspect of the nature versus nurture principle is called the attachment theory, which views the bond between mother and child as being an innate process that ensures survival. It is a biological need that has ensured the survival of many species including the human race; because of the need to protect and be protected humans as a species has been able to endure. It is also a psychological need to want to be cared for as well as care for others a study done by Harry Harlow (1950s). The concept of nurture focuses mainly on the effect that the environment has on the development of human beings and whether it is more important than nature. Several studies have been generated to try and settle the ongoing debate of nature versus nurture.

As technology continues to evolve, our understanding of sickness and disease grows as well. Modern day technology is able to tell doctors what caused the disease and in ideal situations how to cure it. Recent scientists have begun to look at the desire to kill as a disease. This theory poses an interesting concept that if it is a disease, then maybe there is a cure that prevents serial killers from killing. In Christer Claus and Lars Lidberg’s article they look at the desire to kill as a disease. The article states that while using Schahriar Syndrome as a model, they are able to explain even the most vicious human behaviours, such as planned and repeated homicide (Claus/Lidberg 428). This disease is broken down into five main characteristics: omnipotence, sadistic fantasies, ritualized performance, dehumanization, and symbiotic merger. These five traits are not only common among people with the disease, but among serial killers as well (428). The article states that after a successful killing, the killer is surprised. When the killer is able to get away with murder, a sense of amazement consumes them. Once the killer has repeatedly killed their victim and escaped the authorities, they begin to feel like they are omnipotent. As time goes on, over fifty percent of serial killers experience sadistic fantasies that make them want to keep committing the crimes. Each killer uses their success and sadistic fantasies to form a certain ritual. They begin to believe that if they are

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

This literature review focuses on serial killers from a psychological viewpoint while trying to answer the question, “Are serial killers born to kill or are they bred to kill?” Firstly, this review will define a serial killer and the different kinds of killers, then it will take a look at different case studies of children who fantasized about mass killing and identify similarities between the cases attempt to find a way to possibly prevent their fantasies from becoming reality. The debate of nature vs. nurture is also discussed as psychologists and researchers come to the conclusion that environmental factors play a bigger role in the developmental character of a person than genetics, but there is still no definite answer as to why some individuals grow up with the urge to murder other people and/or animals.

The question of whether or not man is predetermined at birth to lead a life of crime is a question that has been debated for decades. Are serial killers born with the lust for murder, or are their desires developed through years of abuse and torment? Many believe it is impossible for an innocent child to be born with the capability to commit a horrible act such as murder. But at the same time, how could we have corrupted society so much as to turn an innocent child into a homicidal maniac? Forensic psychologists have picked apart the minds of serial killers to find an answer as to what forces them to commit such perverse acts. Their ultimate goal is to learn how to catch a serial killer before

This documentary specifies that there is no easy answer to what is going on inside the mind of killers, and we cannot simply place these individuals into “neat diagnostic boxes” that explain why their actions turned so violent. However, the investigators present research studying different avenues regarding ways to “predict” the likelihood that an individual will commit violent crime, will maintaining that no method is perfect. Throughout the presentation, viewers are offered mountains of research highlighting a mix of nature and nurture ranging from neurologists from Harvard studying brain patterns affected by genetics, to psychologists studying maternal care and attachment during infancy.

Patricia S. Churchland 's book entitled Braintrust: What Neuroscience tells Us About Morality, takes us on a walk through the scientific advances in evolutionary biology, genetics and neuroscience that have lead us to the question of wether morality can be explained or justified by science. The goal being an attempt at creating a framework for which to understand human morality. Churchland, a professor at the University of California San Diego in her book asks what is morality? Is it divinely inspired, or instinct, or an abstract set of rules? She argues, that a real understanding of morality begins with an understanding of the brain.

Introduction: This investigation examines the biological causes for serial killers’ psychopathic tendencies and examines those same biological factors in both men and women to find the correlation between a higher rate of male serial killers and the biology behind their actions. It is imperitave to first know what a serial killer is, and what makes them such a cold fish. There are sections of the brain that do have control over a human being’s personality, where that individual can either develop into an average person or join the other one percent of psychopaths living in the world today (due to physical damage or chemical imbalance in the brain). These specific sections of the brain are different in males then in females, some components of the brain vary in size etc. between sexes. It is crucial to have all these pieces, with this information its then possible to form a conlusion to the surfaced question.

The link between morality and human nature has been a progressive reoccurring theme since ancient times (Prinz, 2008). Moral development is a characteristic of a person’s general development that transpires over the course of a lifetime. Moral development is derived by a wide variety of cultural and demographic factors that appear to influence morally relevant actions. Turiel (2006) defined morality as an individuals “prescriptive judgments of justice, rights, and welfare pertaining to how people ought to relate to each other.” Individuals’ moral judgments are frequently considered to be a product of culturally specific controls that provide a framework for behavioral motivations that are sensitive to the effects of gender, education, religion and politics (Banerjee, Huebner & Hauser, 2010). While several approaches have been utilized to examine the interaction of multivariate contributors to fundamental moral differences such as: disputes about family life, sexuality, social fairness, and so on, research has suggested that ideological considerations have provided a potent and diverse explanation for the polarization of contrasting views (Weber & Federico, 2013).

The events of the past can hold a great influence on the actions and behaviors of the future. From being raised in a supportive and loving home, to one that is full of neglect and abuse, each event can potentially impact the future of an individual. In the case of serial killers, there has been some debate on whether the evil ones are made or born; does it happen because of a genetic factor, environmental factor, or is it simply they addicted to the feeling of slaughtering another individual’s life? Although, the most important key in finding the truth deals with the past and shapes the outcome of the future. Upon viewing in a psychological stance, there is no clear understanding of why one aspect that most serial killers share, namely

In the last century the majority of Moral Psychology has been focussed on reason and its role in the production of moral judgement. The use of reasoning

In this paper I will be discussing the topic of morality and where it comes from, and how it is connected to the cosmological argument of how the universe came into existence. Morality is defined as principles concerning the distinction between right and wrong or good and bad behavior. There are two sides to this argument. One being that morality comes from a higher being or God, and the second that we create it ourselves in our genetic programming or conscious, leaving the idea of the existence of God impossible. There are various theories and dilemmas that give insight to the issue, and many philosophers, scientists and

Would you describe a dog as capable of being evil? Or a cat? Or a chimpanzee? Most likely you could not. We humans belong to the taxonomic kingdom of Animalia and are therefore animals. Our species has evolved from animals that looked and acted more like the modern chimpanzee than we do. So at what point did we go from being creatures of instinct do developing the concept of morality? A great deal of literature has been written about morality, examples of which can be located in fiction and non-fiction as well as in scientific, theological and philosophical fields. Specific examples include the bible, as well as the writings of Plato (c. 424-348 BCE), Niccolò Machiavelli (1469-1527) and John Steinbeck (1902-1968). Morality is a trait that

Frans de Waal begins his argument by first stating the question as to whether or not a human’s moral actions originated from the psychological and behavioral nature of our evolutionary ancestors. He concludes this thought by saying that our moral actions do, in fact, originate from the psychological and behavioral nature of our evolutionary ancestors. De Waal further argues that the foundations of human morals are found in the primates of today. They are composed of actions and emotions whose evolutionary role assists us in our social organization and unity. In the beginning pages of his book, De Waal
