The debate on the nature versus nurture is one that has been taking the center stage whenever the psychologists try to unearth the underlying reasons for the serial criminal to involve in the crime activities. Nature focuses on the genetic composition that is determined by the DNA strands. It is mainly inherited from the parents. Nature mostly determines one’s personality, traits and their predisposition. On the other hand, nurture refers to the behaviors that one develops as a result of their interaction with the surrounding environment. Nurture change from time to time depending with the environment that a person is in. Nurture may be viewed from the perspective of one’s bringing by their parents, the influence from the parents, the cultural aspects they learn as they grow and the traits that they inherit from their friends.

The debate of nurture versus nature has perhaps found its place whenever discussion about the serial killers. Ideally, serial killer refers to a person who has at diverse events murdered more than three individuals on cold blood. Historically, serial killers have been associated with either been born like that or develop the behaviors in the course of their growth (Miller, 2014). The study conducted with the 200 participants, however assists in understanding some of the reasons why an individual can turn to be a serial killer despite the harsh punitive measures being taken against the accused people.

Literature Review

Much of the literature points out that the tendency of becoming a serial killer is either in nature or in nurturing. According to Theravive, serial killing is a behavior that makes people to ask several questions. The behaviors leave many wondering the genesis of the behavior and therefore, it becomes necessary to explore whether it is an issue that is based on nature or nurture (TheraviVe). Apparently, there seems to be no definitive explanation as to why people turn to be serial killers. Some feel that nurture determines the behavior of an individual while others feel that behavior is determined by nurture and others feel that the behavior is determined by both. According to Tayler Slavatore both the nature and the nurture determines the behaviors of the serial killer. The only difference is seen when it comes to measuring the magnitude of this heinous act. (Tayler, 2015).

Britanny Richarz intimates that serial killers can be categorized among the individuals who have the Antisocial Personality Disorder. Nature factors that make one to be a serial killer include; physical abuse, sexual abuse, neglect among many others. Similarly, the genetic composition of an individual plays central role in shaping a person’s behavior. (Richarz, 2018). In most instance, the serial killer will murder an individual with the aim of fulfilling their own gratification. Serial killers are driven by psychological gratification at the time they are murdering someone. According to Hayriye, becoming a serial killer is an unfortunate incidence that is attributable to both the nature and nurturing. (Haryiye, 2015). However, these researches are full of flaws since they do not comprehensively focus on to why a person may turn to be a serial killer. This gap will be filled by conducting the current research. By its nature, the current research seeks an affirmative answer on to whether serial killing is in nature or is in one’s nurturing.



During the research, the sample will be 200 participants (100 females and 100 males). The participants will be men and women who have been convicted for being involved in serial killing either individually or collectively. The participants will have consented voluntarily to be asked the questions that will lead to the research conducted. It will be optional for the participants to reveal or hide their identities. However, nothing will be done to prejudice the participants repute in the society. All the participants will be 18 years of age therefore they can make a viable decision while participating in the research.

Research design

In the course of the study, both the primary and secondary methods will be applied. As part of primary method, the participants will be asked to give four major reasons as to why they turned to be serial killers. Moreover, they will be asked to explain the feelings that made them execute the heinous and gruesome murdering. For the participants who may be hostile to the interviewer, they will be given some questionnaires. The questioners will be structured in such a way that the participant will record the major reasons as to why they turned to be the serial killers and what they think ought to have been done to help them change or avoid carrying out the series of killing they have been involved in. In terms of secondary sources, the research will concentrate on the publications which touch on the issues of serial killers extensively.


In the course of the study numerous measures will be employed. Most of these measures have been applied in the previous researches and their results have been impeccable.

Rehabilitation reports: The rehabilitation institutions will be a source of credible information regarding the serial killers. It will furnish the research with the information as to why the killers were involved in the series of murders that led to the conviction.

Social groups: Members of the general society will be asked information relating to the serial killers. They will be required to give a narration of how they know the individuals and how they used to behave before they turned into serial killers. Furthermore, they will be asked to give an account on how long they have known the participants and the behaviors they portrayed in the society.

The local administration will be of vital importance during the research. It will offer information relating to the criminal history of the participants. They will be required to give an account on whether the participants have ever been involved in committing other crimes whether felony or misdemeanor.

Data Analysis

Scale reliability among the serial killers will be the basis for the preliminary analysis of the research. Several factors will be put into consideration when weighing the feedback given by the participants. For instance, it will be important to consider the family history in the commission of the crime and the prevalence of the crimes in a given locality. Comparison will be made between the feedback given between the female and male participants. This will be paramount in basing the research in terms of gender as a factor.

The hypothesis of the research is that involvement in serial killing is a culmination of both nature and nurturing aspect (Keatley, 2018). As such, the blame should not be wholly direct5ed towards the serial killer rather one should analyze the underlying factors. The factors are either intrinsic or extrinsic in nature. These factors will help one to clearly understand the rationale behind the involvement in the serial killing.


In a nutshell, serial killing is perhaps one of the scariest involvement. The research will seek to unravel the underlying factor that makes one turn into a serial killed. Guided by the research methodologies applied when interviewing the 100 participants, the research will assist the audience to appreciate how nature and nurturing shaper the serial killers. Furthermore, it will give a clearer understanding on the root cause of the serial killing. This will make the general society take precautionary measures in case they notice some pecuniary behaviors with particular individual.
