When people encounter shocking acts of cruelty, manipulation, or obsessive behavior, they often reach for two explanations. One explanation is psychological: the person must be mentally ill. The other explanation is moral: the person is evil. These explanations offer a kind of comfort because they simplify the problem. If destructive behavior is the result of mental illness, it can be understood through psychology and possibly treated. If the behavior is evil, it can be condemned and punished. However, many real-life cases resist these simple categories. Some individuals appear both irrational and calculating at the same time. Their actions may show signs of psychological instability while also involving deliberate choices that harm others.
The documentaries The Perfect Neighbor and High School Catfish explore this unsettling territory. In both films, individuals behave in ways that disturb viewers because their actions seem both obsessive and intentional. Conflicts escalate beyond reason. Deception and manipulation play central roles. At the same time, the people involved often feel deeply wronged, isolated, or misunderstood. Their sense of grievance becomes a powerful narrative that justifies their behavior in their own minds. As the stories unfold, viewers are left asking a difficult question: Are these individuals primarily suffering from mental illness, or are they morally responsible for destructive actions that reveal something darker about human nature?
These documentaries also highlight the role of loneliness, resentment, and social alienation. Individuals who feel rejected or humiliated may develop a deep sense of grievance toward others. Without meaningful relationships or healthy outlets for frustration, those grievances can intensify over time. Emotional pain can slowly transform into anger, suspicion, and obsession. In some cases, people begin to see themselves as victims of a hostile world. When this happens, harmful behavior may feel justified to them—even when it appears shocking or cruel to outsiders.
At the same time, manipulation and deception complicate the psychological explanation. In High School Catfish, elaborate lies and fabricated identities are used to control and emotionally manipulate others. In The Perfect Neighbor, conflicts escalate through a pattern of hostility and retaliation. These behaviors often appear strategic rather than purely irrational. This raises an important question: when someone carefully constructs deception or escalates conflict, does that suggest deliberate moral wrongdoing rather than mental illness? Or can manipulation itself be a symptom of deeper psychological disturbance, such as narcissism, obsession, or a need for validation?
Write a 1,200-word argumentative essay that explores the blurred line between mental illness and evil as it appears in The Perfect Neighbor and High School Catfish. Your essay should develop a clear thesis that explains how these documentaries challenge the simple distinction between psychological disturbance and moral responsibility.
Your introduction must include a thesis with mapping components. This means your thesis should clearly state your main argument and identify the key reasons that will organize your body paragraphs.
Example thesis with mapping:
The disturbing behavior portrayed in The Perfect Neighbor and High School Catfish demonstrates that the boundary between mental illness and evil is often blurred because intense loneliness can distort perception, personal grievances can justify cruelty, and deliberate manipulation allows individuals to transform emotional pain into calculated harm.
In this example, the mapping components are:
● loneliness and social isolation
● grievance and resentment
● manipulation and deception
Each of these would become a body paragraph in the essay.
Your essay should include the following elements:
• A clear thesis with mapping components
• Analysis of both documentaries
• Specific examples from the films that support your argument
• A counterargument that challenges your thesis
• A rebuttal defending your position
• A concluding paragraph that reflects on what these cases reveal about human behavior and modern society
Possible directions for your argument include:
• destructive behavior may emerge from both psychological disturbance and moral choice
• loneliness and grievance can transform emotional pain into cruelty
• manipulation and deception suggest deliberate moral responsibility
• society sometimes labels disturbing behavior as mental illness in order to avoid confronting the reality of evil
• disturbing actions may result from a complex mixture of psychological vulnerability, social isolation, and moral failure
Your goal is not simply to summarize the documentaries but to analyze what they reveal about the complicated relationship between mental illness, moral responsibility, and destructive human behavior. In your conclusion, reflect on what these stories suggest about how society should understand and respond to actions that appear both psychologically disturbed and morally troubling.
Helpful Definition: “The Hero Delusion.”
It’s the phenomenon in which people commit harmful acts while believing they are the protagonist in a moral drama. Both documentaries actually illustrate that pattern remarkably well.
Personal Engagement Building Block 3
For your first paragraph, write a 200-300-word profile of someone you know—or a friend of a friend—whose behavior could reasonably be described as morally troubling, destructive, or reprehensible. Begin by vividly describing the person’s actions and their impact on others. While it may be tempting to condemn the behavior outright, the purpose of this paragraph is not simply to judge the individual but to explore the difficulty of explaining why they behave as they do.
As you develop the profile, consider competing interpretations of the person’s conduct. Some observers might view the individual as fundamentally immoral or “evil,” arguing that their actions reflect selfishness, cruelty, or a conscious disregard for others. Others might suggest that the behavior is rooted in psychological disorders, trauma, personality pathology, or mental illness. Use specific details to illustrate why the person’s actions resist simple explanations and raise difficult questions about moral responsibility, free will, and human behavior.
Your paragraph should ultimately establish the central tension of your essay: whether certain forms of harmful behavior are better understood as evidence of moral corruption, psychological dysfunction, or some combination of both. The goal is not to resolve the debate but to introduce a complex case that invites further analysis.
Argumentative Engagement Building Block 3
Write two paragraphs: a thesis paragraph and a counterargument-rebuttal paragraph.
Your thesis paragraph should present a clear, arguable, and defensible claim that answers the central question of your essay. The paragraph should not merely announce a topic but establish a position that reasonable people could debate. After stating your thesis, include mapping components that identify the major points your body paragraphs will use to support your argument. These mapping components should provide readers with a clear roadmap of your essay’s structure and reasoning. Your thesis paragraph should be approximately 200 words.
Your counterargument-rebuttal paragraph should address a legitimate objection to your thesis. Begin by clearly and fairly explaining a viewpoint that challenges your argument. Demonstrate why thoughtful readers might disagree with your position and how their concerns complicate your claim. After presenting the counterargument, write a rebuttal that responds to those objections. A strong rebuttal may concede valid points made by the opposing side while demonstrating that, on balance, your argument remains more persuasive. It may also alleviate concerns by clarifying misconceptions, introducing additional evidence, or identifying important information that the opposing side overlooks. The goal is not to dismiss opposing viewpoints but to engage them thoughtfully and strengthen your overall argument. Your counterargument-rebuttal paragraph should be between 200 and 250 words.
