What Is Sadism?

Have you ever heard someone say, “That person enjoys hurting others—they must be a sadist”? The word gets thrown around a lot, but there’s more to it than just being mean or cruel. At its core, sadism is when someone feels pleasure—often emotional or sexual—from causing pain, discomfort, or humiliation to others.[1] That might sound intense, but here’s the thing: not all sadistic behavior is extreme or even intentional. In fact, some people might show small, subtle signs and not even realize it.[2] The term “sadism” actually comes from the name of a French writer—Marquis de Sade—who was known for writing about violent sexual fantasies in the 1700s.[3] [4] 

Is Sadism a Disorder?

It depends. A lot of people have occasional sadistic thoughts or behaviors—like enjoying dark humor or liking a bit of control in certain situations. That doesn’t mean they have a disorder. But in some cases, sadism can show up in more harmful or persistent ways. Here’s a quick comparison:

Term

What It Means

Is It a Disorder?

Everyday Sadism

Mild enjoyment of others’ discomfort (like trolling or intentionally provoking negative reactions)[5]

No

Sadistic Personality Traits

More regular patterns of cruelty, control, or dominance (like bullying or using humiliation as a control tactic)

Not a clinical disorder[6]

Sexual Sadism Disorder

Ongoing, intense sexual arousal from hurting others—especially if it causes harm and acted on non-consensually

Yes (in DSM-5)[7]

In short, context matters. It’s not just what someone does, but why, how often, and whether anyone is getting hurt.

Psychological roots of sadistic personality traits, showing complex developmental influences

What Causes Sadism?

Like most things in psychology, it’s not just one reason. Sadistic traits usually come from a mix of things—how someone grew up, what they’ve been through, and even brain wiring. Here’s what studies suggest:

  • Childhood trauma**:** People who felt powerless or were mistreated as kids might grow up craving control.[8]
  • Learned behavior**:** If someone grew up seeing others act in a manipulative or hurtful way, they might copy that behavior later.[9] 
  • Biology**:** Brain scans show that some sadistic individuals may have differences in how they process empathy and rewards, which could make causing pain feel rewarding to them.[10]
  • Personality**:** Sadism often goes hand in hand with traits like narcissism and not feeling guilty for hurting others.[11] 
  • Need for control or dominance: Sadistic behavior can stem from a strong desire to feel powerful or superior, especially if the person feels insecure or powerless in other areas of life.[12]

One 2013 study found that people with sadistic traits were more likely to choose tasks that involved harming insects—even when they didn’t have to. It’s called “everyday sadism,” and it shows how subtle these behaviors can be.[5]

Being curious about sadism or your own thoughts doesn’t mean something’s wrong with you. It’s actually a healthy sign that you’re trying to understand things better — and in any relationship, what really matters is mutual respect, clear boundaries, and emotional safety.

What Does Sadism Look Like? (It’s Not Always About Violence)

Sadism isn’t always about physical violence. It can show up in subtle or socially acceptable ways that still cause real harm. Here are some signs to look for—especially if their behavior leaves you feeling uneasy: 

  • Enjoying others’ pain or discomfort – whether physical, emotional, or social.[13] 
  • Mocking, humiliating, or putting others down regularly, especially in front of others — often by targeting their insecurities to make them feel ashamed.[13]
  • Get defensive or mocking when you express hurt, instead of showing concern.[13] 
  • Power play and control – feeling superior by making others feel small, afraid, or uncomfortable especially in relationships.[13]
  • Lacks guilt or empathy after hurting someone.[13]
  • Seeking conflict — thrives on drama, tension, or arguments, or pushing people’s boundaries.[13]
  • Hidden aggression – using sarcasm, manipulation, or passive-aggressive behavior to undermine or harm others.[13] 
  • Enjoys cruelty framed as “just a joke”.[13] 

If any of this sounds familiar, it might be time to take a step back and reflect on how you feel around this person.

Sadism in Relationships: What’s Healthy vs. What’s Harmful?

Not all sadistic behavior in relationships is abusive. The key difference lies in consent, communication, and intent. Here's a quick comparison to help you identify the line between safe exploration and harm: 

Aspect

Consensual Sadism (Okay)

Harmful Sadism (Not Okay)

Consent

Freely given, enthusiastic, and ongoing

Absent, unclear, or pressured

Communication

Open discussions before, during, and after

Manipulative, one-sided, or completely lacking

Boundaries

Clearly set and always respected

Ignored, dismissed, or constantly violated

Emotional Safety

Both partners feel safe, cared for, and emotionally supported

The other person feels unsafe, emotionally drained, humiliated, or constantly hurt

Intent

Mutual exploration for shared pleasure

Used to dominate, punish, or control the other person[14]

Aftercare

Prioritized to ensure comfort and connection

Neglected or seen as unnecessary

Important note: BDSM ≠ abuse: Sadism is not like the power plays of masochism or consensual BDSM, where healthy dynamics are rooted in mutual trust, respect, and clear boundaries based on clear consent.[15] [16] [17] 

Personal boundaries and self-protection against manipulative and harmful behavioral patterns

How to Cope if Someone’s Sadism Is Hurting You

If you’re dealing with someone who seems to enjoy causing harm — emotionally, verbally, or sexually — it can take a serious toll on your mental health. Whether it’s a partner or someone else in your life, here’s how you can start protecting yourself:

  • Set clear boundaries and stick to them - You have every right to say “No” or “That’s not okay with me.” If someone continues to cross the line after you’ve clearly set boundaries, that’s not a miscommunication — it’s a red flag.[18]
  • Seek support from a therapist or counselor - A mental health professional can help you process what’s happening, validate your feelings, and guide you toward practical ways to stay safe — emotionally and physically.[19] 
  • Document patterns of manipulation or abuse - Keep a private record of incidents, how they made you feel, and any patterns you notice. This can help you see things more clearly and support you if you decide to seek help or take action later.[20]
  • Prioritize your emotional safety - If you feel anxious, drained, or unsafe around someone — that’s reason enough to take a step back. Your peace matters, even if the other person doesn’t see it that way.[19]
  • Don’t minimize what you’re experiencing - It's easy to second-guess yourself, but if something feels wrong, it probably is. Trust your gut — your discomfort is valid.[20]

Most Asked Questions

How can I tell if my partner’s behavior is sadistic or just dominant?

If their behavior hurts you emotionally or physically, or makes you feel afraid or powerless—especially without your consent—it may be sadistic or abusive.

Can someone be a sadist without realizing it?

Yes. Some people may not realize their enjoyment of power or humiliation is part of sadistic behavior—especially if it’s normalized in their environment.

Is sadism always linked to sexual behavior?

No. While some sadistic traits appear in sexual contexts, others show up in emotional or social situations — like belittling others, bullying, or enjoying someone’s discomfort.

What is the difference between sadism and BDSM?

Sadism in a consensual BDSM context involves mutual agreement, safety, and respect. In contrast, non-consensual sadism causes harm or distress without the other person's consent.

Is it okay to have sadistic fantasies?

Having fantasies doesn’t make someone bad or abusive. Fantasies are normal, and what matters most is how you act in real life—especially in relationships.

What is a masochist vs a sadist?

A masochist enjoys receiving pain or humiliation, while a sadist derives pleasure from causing it. In consensual contexts (like BDSM), these roles are understood and agreed upon by both people.
