8 Clear Signs You’re Dealing With a Deeply Toxic Person

If you’ve ever experienced that sudden, chilling feeling when your gut instinct warns you that a person might be “off” or even downright harmful, you know the immediate necessity of paying attention. This profound sense of unease can strike anywhere—from a busy, sunny coffee shop to an anonymous corporate office. One moment you’re simply living your life, and the next, your intuition kicks in, serving as an ancient, biological alarm system telling you something is fundamentally wrong. Maybe it’s a stranger whose intentions don’t sit well with you, or perhaps it’s a friend or romantic partner who is subtly, yet systematically, trying to manipulate you for their own personal gain. Whatever the situation, recognizing these red flags early is an act of essential self-preservation before the dynamic can turn genuinely damaging.

It’s vital to maintain perspective: not everyone who seems a little awkward or socially uncomfortable is necessarily “evil” or harmful. Many people have endured tough experiences, past trauma, or currently struggle with unmanaged mental health issues, and they are simply trying to navigate life’s complexities. As long as no one is being hurt or emotionally upset, sometimes the wisest course of action is simply to nod politely, keep a healthy distance, and walk away. But the focus here is on those who truly mean harm—those who seem actively “out to get you,” or whose persistent behavior drains your energy and diminishes your sense of self-worth. These are the individuals exhibiting deeply toxic traits, and here are eight crucial warning signs to watch for so you can protect yourself and stay emotionally and physically safe.

I. The Core Indicators: Delight, Isolation, and Prejudice

1. When Someone Revels in Misfortune (Schadenfreude)

This is one of the most immediate and unsettling signs of emotional toxicity: a partner or acquaintance who finds obvious delight in the suffering or failure of others. You stumble, miscalculate, or fail at a professional goal, and they burst out laughing, their amusement disproportionate to the event. Bad news flashes across the TV, detailing a public misfortune, and suddenly they’re grabbing the popcorn, their attention rapt and their mood inexplicably elevated. This unsettling delight in others’ misfortune is called schadenfreude—a German term that means feeling smug satisfaction, or exquisite joy, from someone else’s troubles.

As Adrian Furnham, Ph.D., explains in Psychology Today, it’s “exquisite joy and smug satisfaction from contemplating and reveling in the misfortune of others.” While a mild, fleeting moment of schadenfreude is normal human psychology—we all laugh when someone slips harmlessly—a person who consistently, openly, and profoundly delights in the pain and failure of others signals a severe deficiency in empathy and a problematic reliance on comparing their own success to the failures of those around them. This calculated, cold-hearted joy is profoundly creepy and a major red flag.

2. Limited Social Circle (A Network of Utility)

It might not come as a shock that people who show these kinds of deeply negative, self-serving traits often don’t have many genuine, long-standing friends. But the reason for this isolation is usually not simple social awkwardness; it is rooted in their transactional view of relationships.

According to Marcina Cooper-White, people with harmful, toxic intentions often only seek friendships when there’s something tangible in it for them—whether it is professional advancement, financial gain, social status, or constant, uncritical emotional support. Their relationships are networks of utility, not genuine connection. Otherwise, they tend to actively push others away or avoid making the vulnerable, reciprocal investment required for genuine connection. This unwillingness to form honest, deep bonds is a profound indicator that their primary motivation is self-interest and exploitation, not shared companionship.

3. When Racism and Sexism Show Up (The Closed Mindset)

While racism and sexism are complex social issues that do not always perfectly align with interpersonal toxicity, their presence is a fundamental indicator of a closed, rigid, and profoundly disrespectful mindset. It’s important to address racism and sexism directly because they are clear signals of an individual’s inability to grant basic humanity to others.

People who engage in overtly racist or sexist attitudes are fundamentally closed off to the basic truth that everyone deserves equality, respect, and dignity. That mindset is not only outdated and socially unacceptable; it demonstrates a profound, active lack of empathy and a willingness to dehumanize others based on arbitrary characteristics. This cognitive and emotional rigidity—the inability to change a harmful view despite evidence—is a clear predictor of toxicity in close relationships, as the person will inevitably project their inherent disrespect and discriminatory beliefs onto their partner or friends.

II. The Emotional Vacuum: Empathy and Remorse

4. Emotional Disconnect: The Absence of Empathy

A person who engages in harmful behavior—whether it’s harming animals, consistently lying for personal gain, or manipulating family members—often shares a core, defining trait: a profound lack of empathy.

Empathy is the cognitive and emotional ability to understand and share another person’s feelings, explains Susan York Morris. It is the human faculty that allows us to feel pain when we see others suffer. This emotional disconnect often goes hand in hand with a profound, terrifying lack of remorse, making it a particularly alarming characteristic. If a toxic individual cannot feel your pain, they have no intrinsic reason to stop causing it. The absence of this emotional circuitry is a critical indicator of psychopathic or narcissistic tendencies.

5. When They Refuse to Own Their Mistakes (The Blameless Narrative)

Most people, after having a bad day and unintentionally taking it out on a partner—being cranky or failing to listen to a friend’s problems—would feel some immediate guilt, right? This remorse is the conscience mechanism that drives relational repair. But cold-hearted, toxic individuals rarely, if ever, experience that remorse.

As Mike Adams explains, “Their brains simply lack the circuitry to process such emotions.” This means they can betray, threaten, or inflict harm on others without a second thought, because the act causes them no personal moral discomfort. A toxic person will perpetually refuse to own their mistakes, instead externalizing blame, twisting the narrative, or inventing justifications for their actions. This complete inability to feel or process guilt is a definitive, flashing red flag indicating a fundamental deficit in moral and emotional accountability.

III. Manipulation and Control Tactics

6. Mocking or Minimizing Your Concerns

Watch out for people who turn your legitimate fears or worries into a cruel joke or a performance of their own superiority. If you’re feeling anxious about landing a new job, worried that your best friend might be upset with you, or simply dealing with a moment of self-doubt, your partner or friend should offer sincere support, reassurance, and validation—not mock you.

As Elise Williams puts it, when you need comfort, a toxic person will often do the opposite of what is supportive. When someone regularly makes you feel silly, overly sensitive, or ashamed for having normal human emotions, that is a serious, corrosive red flag. This behavior is designed to minimize your perspective and elevate theirs, effectively training you to suppress your feelings and rely solely on their judgment.

7. When Someone Tries to Control You (The Reality Bender)

Manipulation is another major red flag—and a clear, systemic sign that someone does not have your best interests at heart. The tricky and dangerous part is that manipulative people are often extremely skilled at what they do.

As Darlene Lancer, JD, MFT, explains, manipulative people are masters of cognitive distortion and gaslighting: “Manipulators often voice assumptions about your intentions or beliefs and then react to them as if they were true, in order to justify their feelings or actions—all the while denying what you say in the conversation.” This tactic is a form of emotional jujitsu, twisting your reality to gain control. Anyone who consistently and deliberately twists reality, denies your memory, or uses psychological pressure to gain control over your decisions, finances, or social life is not someone you want, or can safely afford, to keep in your life.

8. When Everything They Say Feels Off (Calculated Deception)

Everyone tells the occasional minor social lie—a “white lie” about why they were late or why they can’t make it to dinner. That is a normal, if sometimes ethically questionable, aspect of social lubrication. But truly toxic people take lying to another level entirely. They often use deception as a systematic tool to manipulate and control others, rather than as an occasional social convenience.

In fact, some may even start off by being unusually honest—often about irrelevant things—to quickly gain your trust, only to subtly slip in lies later when it benefits them most. As Jeff Wise explains in Psychology Today, this tactic makes their deception even more effective and harder to detect, because the baseline trust they established makes you doubt your own instincts when the major lie finally appears. This is not just dishonesty—it’s deeply calculated, strategic manipulation designed to make you vulnerable and pliable.

IV. The Necessity of Self-Protection

If you find yourself shocked after reading this list, remember that not everyone who acts badly does so out of pure malice; some are dealing with the chronic, debilitating aftermath of past trauma or unmanaged mental health conditions. Understanding this context is important for maintaining empathy and avoiding blanket judgment.

However, when confronted with the sustained, compounding pattern of the eight traits listed above—the lack of remorse, the constant manipulation, the contempt for others’ feelings—the most critical response is not to diagnose or cure, but to protect yourself. Your intuition is your most valuable asset. The moment your gut tells you something isn’t right, you must listen, establish clear boundaries, and safely create distance from the deeply toxic individual.
