Abstract
The occurrence of homicide, with all its complexities, has fascinated scholars and the public for centuries. This paper explores the psychological underpinnings of homicide, from premeditated killings to crimes of passion. It reviews the existing literature on the topic, drawing on a range of peer-reviewed journal articles to shed light on what motivates people to commit murder. Through this analysis, the paper uncovers various factors contributing to homicide, including personality traits, mental health issues, social and environmental factors, and cultural norms. Ultimately, the paper argues that a comprehensive understanding of homicide requires consideration of these various factors and that this understanding can help us to develop more effective strategies for preventing and addressing this complex phenomenon.
Introduction
Homicide is intentionally killing one person by another, one of the most extreme forms of interpersonal violence. Despite its gravity, homicide is surprisingly common worldwide, with an estimated 475,000 homicides occurring globally in 2019 alone (Stickle & Felson, 2020). Understanding what motivates people to commit murder is an important area of research with potential implications for criminal justice, public health, and social policy.
This paper aims to explore the psychological underpinnings of homicide, drawing on a range of peer-reviewed journal articles to investigate what motivates people to commit murder. The paper begins by reviewing some of the key theoretical frameworks developed to explain homicide before discussing the various factors that have been found to contribute to this complex phenomenon.
Theoretical Frameworks
Several theoretical frameworks have been developed to explain homicide, each highlighting different aspects of this complex phenomenon. One of the most influential of these frameworks is the social learning theory, which proposes that individuals learn violent behavior through exposure to violent models, either in person or through media (Solakoglu & Yuksek, 2020). According to this theory, individuals exposed to violence are more likely to engage in violent behavior.
Another important theoretical framework is the general aggression model, which posits that aggressive behavior results from a complex interplay between cognitive, affective, and environmental factors. According to this model, the likelihood of aggressive behavior is influenced by various factors, including personality traits, situational factors, and cultural norms. In addition, some researchers have proposed evolutionary theories of homicide, which suggest that homicide may be an adaptive behavior that has evolved to enhance the reproductive success of individuals and their kin. According to these theories, homicide may be more likely to occur in situations threatening an individual’s reproductive success, such as in cases of infidelity or sexual competition (Silberberg & Thyer, 2023).
Another important theoretical framework for understanding homicide is the strain theory. This theory posits that individuals are more likely to engage in violent behavior when they experience strain or frustration due to the discrepancy between their aspirations and the opportunities available. Strain can result from various factors, such as poverty, unemployment, or social inequality. According to this theory, individuals unable to achieve their goals through legitimate means may turn to violence to obtain their desired outcomes. Control theory also suggests that individuals are less likely to engage in violent behavior when they have strong social bonds and connections to their communities. According to this theory, individuals with strong social ties embedded in their communities are less likely to engage in criminal behavior, including homicide (Hardesty & Ogolsky, 2020). Conversely, individuals who lack social connections and feel disconnected from their communities may be more likely to engage in violent behavior.
Another theoretical framework that has gained attention in recent years is the biosocial theory of homicide. This theory posits that genetic and environmental factors contribute to the likelihood of engaging in violent behavior. The interplay between these factors is crucial for understanding why some individuals are more prone to homicide than others. Biosocial theorists suggest that environmental factors, such as violence or childhood trauma exposure, may trigger genetic predispositions to aggression. This perspective highlights the complexity of homicide as a phenomenon and underscores the need for interdisciplinary approaches to understanding it.
Factors Contributing to Homicide
While theoretical frameworks can help us understand some underlying mechanisms that contribute to homicide, they do not provide a complete picture of this complex phenomenon. Other factors have been found to contribute to homicide, including personality traits, mental health issues, social and environmental factors, and cultural norms. Personality traits have been found to play an important role in the homicide. For example, research has suggested that individuals with high aggression, impulsivity, and sensation-seeking may be more likely to engage in violent behavior (Connolly et al., 2020). Other research has suggested that individuals with certain personality disorders, such as antisocial personality disorder or borderline personality disorder, may also be at higher risk of committing homicide. Mental health issues are another important contributor to homicide. Research has found that individuals with certain mental health conditions, such as schizophrenia, bipolar disorder, and major depressive disorder, may be at increased risk of committing homicide. Furthermore, this does not suggest that all individuals with mental health issues are violent but that certain conditions may increase the likelihood of violent behavior.
Social and environmental factors are also important contributors to homicide. For example, research has suggested that poverty, unemployment, and social inequality may increase the risk of violent behavior. Other research has suggested that exposure to violence in childhood, such as domestic or community violence, may increase the likelihood of engaging in violent behavior later in life (Santacrose et al., 2021). Cultural norms are also an important factor to consider when exploring homicide. In some cultures, violence may be an acceptable way of resolving conflicts or protecting one’s honor. In addition, this can contribute to higher rates of homicide in these cultures.
Similarly, cultural norms around masculinity may contribute to higher rates of homicide among men, who may feel pressure to be aggressive and dominant. Access to firearms is another factor. Research has shown that firearms in a household or community can increase the risk of homicide, as they provide a lethal means of carrying out violent acts.
Furthermore, the role of alcohol and drug use in homicide is another factor. Substance abuse can impair judgment and increase impulsivity, making individuals more prone to violent behavior. In addition, drug-related disputes or transactions can escalate into acts of violence, particularly in communities where drug use is prevalent, or drug trafficking is common. The use of drugs and alcohol has been implicated in a significant proportion of homicides, particularly those that occur in domestic or intimate partner violence situations (Gillard, 2019). In recent years, the impact of technology on homicide has become an emerging concern. The rise of social media and online communication platforms has provided new avenues for individuals to engage in cyberbullying, harassment, and other forms of online violence.
In some cases, this online violence can escalate to physical violence, as individuals may seek to confront or harm those they feel have wronged them online. Using technology in homicide has also raised new challenges for law enforcement and criminal justice systems. Tracing online communications and gathering evidence in these cases cannot be easy.
Finally, the role of societal and cultural factors in homicide cannot be ignored. The way that homicide is portrayed in popular media, for example, may influence attitudes and behaviors around violence. Normalizing violent behavior in media or cultural products may desensitize individuals to the consequences of violent actions, making them more likely to engage in violent behavior themselves. Similarly, the way that homicide is perceived and addressed by society can impact its prevalence. For example, a lack of trust in law enforcement may make individuals less likely to report acts of violence, allowing perpetrators to go unchecked.
Prevention and Intervention
Understanding the various factors that contribute to homicide can help us develop more effective prevention and intervention strategies. For example, reducing poverty and inequality may help decrease the likelihood of violent behavior. Similarly, interventions that address mental health issues and support individuals who have experienced trauma may help reduce the risk of violent behavior. Changing cultural norms around violence and masculinity may also effectively reduce homicide rates (Malhi et al., 2020). Furthermore, this could involve education campaigns, community outreach programs, and efforts to promote alternative forms of conflict resolution.
To effectively prevent and intervene in cases of homicide, it is important to adopt a comprehensive approach that considers the multifaceted nature of the problem. In addition, this involves addressing a wide range of risk factors, including but not limited to poverty, mental health issues, social and environmental factors, and cultural norms. One promising approach to prevention and intervention involves a community-based strategy that involves engaging with local stakeholders, such as community leaders, law enforcement agencies, and mental health professionals. This approach can help to foster a sense of ownership and accountability among community members, leading to greater commitment to reducing the incidence of homicide (Alvarez et al., 2022). Additionally, community-based interventions can be tailored to different communities’ specific needs and cultural contexts, considering their unique risk factors and social norms. Another effective strategy is the use of early warning systems that can help identify individuals who are at risk of committing homicide. These systems can involve a range of tools, such as predictive analytics, threat assessments, and screening tools that can help identify individuals who need intervention. Early warning systems can be particularly effective in identifying high-risk individuals with mental health issues or a history of violent behavior.
Finally, efforts to reduce the availability of firearms and other lethal weapons can also be an important component of prevention and intervention strategies. Moreover, this can include background checks, gun buyback programs, and restrictions on selling and owning certain firearms (Sanchez et al., 2020). Such measures can help reduce the likelihood of impulsive acts of violence and make it more difficult for individuals at risk of committing homicide to access weapons.
Conclusion
Homicide is a complex and multifaceted phenomenon influenced by various psychological, social, and environmental factors. While theoretical frameworks can help us understand some underlying mechanisms that contribute to homicide, a comprehensive understanding of this phenomenon requires a nuanced consideration of the various factors that contribute to it. By better understanding the psychological underpinnings of homicide, we can develop more effective strategies for preventing and addressing this complex phenomenon.
