The short story "The Perfect Murder" by J. Archer is a classic example of a crime story that focuses on the psychology and motives of the murderer rather than on the actual act of killing. The story revolves around a man named Herbert who plans to murder his wife, but things do not go as planned. In this analysis, we will explore the themes of motive and psychological factors that influence criminal behavior. Motive is often considered a crucial factor in understanding criminal behavior. In the case of Herbert, the motive for his crime is financial gain. The story reveals how Herbert is in a dire financial situation due to his inability to find a job and is constantly berated by his wife for his perceived failure. His financial woes are compounded when his wife informs him that she intends to take out a life insurance policy, naming him as the sole beneficiary. Herbert's fear of becoming destitute after his wife's death provides him with the motivation to commit the crime. Psychological factors also play a role in Herbert's decision to murder his wife. The first is a sense of inadequacy that Herbert feels due to his inability to provide for his family. This feeling leads to a sense of desperation, and he begins to fantasize about how his problems would be solved if his wife was no longer alive. The second factor is his anger towards his wife for her constant belittlement, which builds up inside him until he becomes bent on getting revenge. Archer illustrates how personal feelings of inferiority, desperation, and anger can have an impact on the psyche of an individual, leading to criminal behavior. Research confirms that one of the key factors that influence criminal behavior is a person's psychological state, and studies suggest that individuals who experience chronic stress or intense negative emotions are more likely to engage in illegal activities. Another psychological factor in Herbert's decision to murder his wife is his sense of entitlement. He believes that he has been wronged and owes it to himself to take revenge against his wife. In his mind, he justifies the murder as something he deserves, and these self-justifications create a distorted perception of morality and ethics. Furthermore, the story highlights the fact that murder is not always a premeditated act, but rather a decision made in the heat of the moment. Herbert's plan to murder his wife changes when he sees a stranger stalking his house and becomes convinced that the man is planning to rob them. In his panic, he decides to use this opportunity to frame the robber for the murder, which he does by altering the crime scene to make it look like a burglary gone wrong. This sudden change in the plan is an example of how impulsive and reactive behavior can affect criminal decision making. In conclusion, Archer's "The Perfect Murder" reveals how psychological factors such as motives, personal feelings of inadequacy, desperation, anger, a sense of entitlement, and impulsiveness can influence criminal behavior. The story shows that criminal decisions are not always the result of a calculated plan but can be made in the heat of the moment. This analysis emphasizes the importance of exploring the underlying motives and psychological factors that influence criminal behavior to understand the complex nature of human decision-making and how it leads to crime.
