What Are Psychopaths? A Closer Look

Psychopaths are individuals with a personality disorder characterized by traits like superficial charm, high intelligence, pathological lying, lack of remorse, and manipulative behavior. Psychopathy, part of antisocial personality disorder (ASPD), affects about 1% of the population, with higher prevalence in forensic settings [Frontiers in Psychology]. Unlike popular media portrayals, psychopaths are not always violent; many function in society, using charm to mask their emotional differences.

People feel that psychopaths are cold, calculated and remorseless individuals who will do anything to achieve what they want. Even the diagnostic features of psychopathy includes the presence of:

• High intelligence
• Superficial charm
• Poor judgment
• Absence of experience learning
• Pathological lying
• Incapability of love
• Egocentricity
• Absence of shame or remorse
• Grandeurs of self-worth
• Impulsivity
• Manipulative behavior
• Promiscuous sexual behavior
• The absence of self-control
• Criminal behavior
• And a few others

Since these traits are common in psychopathy, the image of the psychopath has become that of a person who lacks any normal human emotions and empathy.

Psychopaths feel too

Psychopaths do feel emotions towards their loved ones. However, their love is different from what can be categorized as normal love. In this article, I will be discussing the emotions that psychopaths feel and how is their emotional quotient is different from what has been deemed to be normal amongst others.

Yes, psychopaths do have feelings even though they are different from what a normal human might experience. If a psychopath is in a room full of people who are experiencing a specific emotion, chances are that the psychopath may not feel the same way. This psychopath will only feel concerned if it is a person that the psychopath truly cares about like their mother, children, spouse, father, pets etc. However, the ability to feel and respond empathetically towards others is absent in psychopaths.

If there is a discussion of a tragedy in the room which has affected millions of people and taken hundreds of lives, everyone in the room may feel sadness towards the incident. However, the psychopath may not feel anything. Some psychopaths are skilled at mimicking human behavior. They may pretend to be sad when actually they do not feel anything.

Biological Correlates of Psychopathy

The behaviors of psychopaths stem from neurobiological differences. Studies show reduced gray matter in the prefrontal cortex and amygdala, areas linked to impulse control and empathy [University of Wisconsin-Madison]. Elevated levels of neurochemicals like cortisol, testosterone, and serotonin contribute to impulsivity, aggression, and sensation-seeking [Neuroscience & Biobehavioral Reviews]. These imbalances explain why psychopaths may struggle to learn from consequences or feel fear like others.

Emotional Experiences of Psychopaths

Contrary to the stereotype of psychopaths as emotionless, they do experience emotions, but in ways distinct from neurotypical individuals. Their emotional range is shallow, often limited to self-focused feelings like anger or pride, with reduced empathy for others [Aeon]. Psychopaths may feel love or sadness for close relationships (e.g., family, pets), but their empathy is selective and often tied to personal gain [HealthyPlace]. Many are skilled at mimicking emotions to blend in, a trait that can make them appear charming or trustworthy [My Florida Law]. This section explores their emotional pain, inferiority complex, and need for stimulation, supported by reader stories.

Do psychopaths feel emotional pain?

Psychopaths can experience emotional pain, particularly from unfulfilled desires for love and connection. Their manipulative behaviors, commitment issues, and lack of empathy often lead to broken relationships, causing genuine sadness [ResearchGate]. Childhood traumas—such as parental neglect, substance abuse, or chaotic environments—may exacerbate this, creating a cycle of isolation. Psychopaths may recognize their impact on others but struggle to change due to impaired fear responses [Max Planck Institute].

Real-Life Scenario: Lily’s Isolation
Lily, a 32-year-old marketing executive, was diagnosed with psychopathy after years of unstable relationships. She felt deep sadness when her partner left due to her manipulative tendencies, as explored in my Healing from Emotional Trauma. Using therapy, Lily learned to identify her pain but struggled to empathize with others. Her story shows psychopaths can feel personal loss, though broader empathy remains limited.

If you look into the childhood history of the psychopath, it may have various indicators of repressed childhood traumas like

• Constant fights between the parents
• Absence of parental attention
• Complete lack of parental guidance
• Chaos in the family
• Substance abuse by parents
• Antisocial behavior by parents
• Divorce amongst parents
• Exceptionally poor relationships
• Awful neighborhoods.

Such people may grow up being prisoners in their own minds. They may also have fewer opportunities compared to others to actually grow and evolve. Many people have dysfunctional family. However, when the dysfunction becomes too much for the child to handle, they may recede in themselves. This most often leads to a psychopathic behavior.

High Inferiority Complex

Despite outward arrogance, psychopaths often harbor a deep inferiority complex, aware their behaviors alienate others. They understand their traits—lying, manipulation, lack of remorse—are stigmatized, leading to internal conflict [ResearchGate]. Some psychopaths hide their true nature to maintain social connections, while others accept isolation, causing dejection. This awareness can drive feelings of inadequacy, especially when comparing themselves to those with stable relationships.

Real-Life Scenario: Rick’s Hidden Struggle
Rick, a 40-year-old lawyer, exhibited psychopathic traits like charm and impulsivity. He felt inferior watching colleagues form close friendships. Rick masked his traits at work but felt empty at home, using my journaling techniques to journal his emotions. His experience highlights how psychopaths grapple with societal rejection.

“Psychopaths are not devoid of feelings; they can experience emotions like anger or pride, but their empathy is limited, often serving their own interests rather than genuine connection,”

– Dr. Abigail Marsh, a psychologist studying psychopathy

Need for Excessive Stimulation

Psychopaths seek high stimulation due to low arousal levels, driven by neurobiological deficits. Their thrill-seeking—through risky ventures or relationships—often fails due to unrealistic expectations [Max Planck Institute]. Charismatic initially, psychopaths lose connections as their true nature emerges, leading to frustration and depression. As they age, this lifestyle causes burnout, worsening emotional frustration.

Real-Life Scenario: Stella’s Burnout
Stella, a 29-year-old event planner, craved excitement through risky social schemes. Her friendships faded when her manipulation surfaced. Therapy helped Stella manage stimulation needs, but burnout led to depression.

Real-Life Scenario: Casey’s Emotional Facade
Casey, a 42-year-old consultant, mimicked emotions to fit in at social events but felt empty afterward. Her sadness stemmed from failed friendships.

When does a psychopath become violent?

There is a limit to everything. Eventually psychopaths feel that they have reached the end of the line. They feel that they cannot return from this point. The most common feeling at this point is that they have cut ties with the people in the normal world. At this edge, psychopaths start to feel that they have nothing left to lose. Thus, they start to show their true colors even if they have repressed it before.

Risk factors associated with violent behavior in psychopaths

There are certain risk factors that contribute to violent behavior in psychopaths. These are:

• Loneliness
• Hidden suffering
• Inferiority complex
• Absence of self-esteem
• Violence and emotional pain

Loneliness, social isolation, having no friends and the emotional pain that’s associated with being alone all the time may proceed the acts of violence in case of psychopathy. Psychopaths start to believe that the entire world is against them, no one will ever understand them and they will always be lonely. This convinces them that if they want something they will have to go get it themselves. They deserve the right to satisfy their needs and special privileges. Therefore, the violence starts when they feel that they have reached a point from where they cannot return any more and they start showing aggressive outbursts. Eventually, as the loneliness and sadness increase, their crimes may not even make sense anymore.

Real-Life Scenario: Ethan’s Breaking Point
Ethan, a 45-year-old mechanic, displayed impulsivity. Years of isolation led to aggressive outbursts, as explored in my Building Resilience After Setbacks section. Therapy helped Ethan manage anger, reducing violent tendencies.

Self-destruction

There are two types of psychopaths. One category of psychopaths target others and the other category target themselves. Once the person starts to believe that life is worthless, they will never achieve anything, they will never have any friends, social connections, and living does not make any sense anymore, they have reached their breaking point. When psychopaths reached this point, they may either end their own life by engaging in drugs, alcohol abuse risky driving etc. Alternatively they may begin to hurt others for pleasure.

Biological basis of psychopathy

In the last few decades, many neurobiological explanations have sprung up defining the traits of psychopathy. It has been observed that psychopaths have an abnormality in the region of the brain that controls fear. The fear sensors are wrongly wired in the case of psychopaths. Their recklessness, hostility, impulsivity and aggressiveness has been explaining by the presence of high levels of many neurochemicals like:

• Monoamine oxidase
• 5 hydroxyindoleacetic acid
• Free thyroxine
• Cortisol
• Triiodothyronine
• Serotonin
• Testosterone
• Hypothalmic-pituitary-adrenal hormone
• Adrenocorticotropic hormone
• Hypothalamic-pituitary-gonadal hormones

Cortisol has been linked to the inability to learn from past experiences and the constant sensation-seeking behavior of psychopaths. Sensation seeking is related to the presence of low levels of monoamine oxidase and high levels of the gonadal hormones. Reduced levels of the grey matter volume have been linked to sensation-seeking behavior.

Because of the above-mentioned neurobiological evidence, psychopathy to a certain level can be considered as a result of neurobiological imbalance. These neurobiological imbalances have created a gulf between the psychopath and everyone else.

Tracking Interactions with Psychopathic Traits

To understand interactions with psychopaths, I’ve created the Guilt Free Mind Psychopathy Self-Reflection Tracker, a downloadable PDF to monitor:

• Emotional Cues: Note observed emotions (e.g., charm, anger).
• Behavioral Patterns: Track manipulation or impulsivity.
• Personal Impact: Reflect on how interactions affect you.

Use this weekly tracker to gain insights and discuss with a therapist.

Is it possible to treat psychopathy?

Some traits of psychopaths, like aggression and impulsivity, can be managed with psychopharmacotherapy (e.g., lithium), neurofeedback, and psychotherapy, with effects seen in some cases within five years [Glenn & Raine]. These reduce symptom intensity but don’t eliminate psychopathy. Neurofeedback lowers arousal, aiding impulse control. Complete cures remain elusive due to entrenched neurobiological deficits.

Real-Life Scenario: Stella’s Treatment Journey
Stella, a 29-year-old artist, struggled with psychopathic impulsivity. Lithium and therapy reduced her aggression, though challenges persisted. She used the tracker to monitor progress, showing psychopaths can benefit from targeted interventions.

Conclusion

Psychopaths have a very different world than the rest of us. They can mimic most human emotions if they want to. However, after a certain point of time, they grow tired and stop acting. This is when psychopaths can truly become dangerous. If they feel that things are never going to improve, they will never have friends or family, they can go off the edge and engage in violent crimes. Certain medications can reduce the traits of psychopathy in psychopaths. However, there is no medication that can completely eradicate psychopathy.
