The More You Crave Revenge, the More It Hurts: Unmasking the Psychology of Revenge
The old saying "a gentleman can wait ten years to take his revenge" captures a psychological phenomenon deeply rooted in human society — revenge. But have you ever wondered what is actually going on inside us when we are seething with resentment, longing for the other person to be punished? At its core, the urge for revenge is an emotional response to feeling unjustly treated. It blends anger, hurt and a sense of powerlessness, and ultimately turns into an impulse to "restore the balance". This state of mind shows up in many guises in everyday life: deliberately sitting on a document a colleague urgently needs at work, pointedly giving a partner the cold shoulder to signal displeasure, even posting a spiteful anonymous comment online — all of these are different expressions of the same psychology.
Yet revenge rarely brings the release we imagine. Carlsmith's research uncovered a paradox: people who carry out revenge not only fail to feel relief, they actually stay mired in negative emotion (Carlsmith, 2008). This is because the act of revenge intensifies our focus on the event that hurt us — like repeatedly tearing open a wound that was about to heal. More ironic still, we tend to overestimate the impact our revenge has on the other person. The "counter-strike" you so carefully designed may, in their eyes, be entirely painless — perhaps not even noticed at all.
The Psychological Roots of the Urge for Revenge: Childhood Experience, Personality Traits and Social Influences
Why are some people especially prone to falling into the spiral of revenge? This is closely tied to our early attachment style. As we grow up, if our primary caregivers are sometimes warm and sometimes distant, a child can easily develop an anxious attachment style. This pattern leaves a person prone to insecurity and a fear of abandonment within close relationships, which in turn inclines them to use revenge as a form of self-protection — an attempt to regain control through a "counter-strike". Research by the American psychologist Michael McCullough and colleagues goes further, pointing out that the human brain has evolved a dedicated cognitive system for handling revenge and forgiveness, in which the function of revenge is to deter potential aggressors, thereby protecting ourselves from being harmed again (McCullough, 2013).
Social and cultural factors cannot be overlooked either. Hong Kong's fiercely competitive urban environment quietly reinforces an "eye for an eye" mindset. An accidental bump on the MTR, or a thoughtless remark in the office, can be read as an intrusion into one's personal domain. The urge for revenge is especially strong when self-esteem has been wounded — for example, when we are publicly humiliated or treated unfairly. At such moments, our brain automatically activates a "moral outrage" mechanism, casting ourselves as the "agent of justice" in an attempt to rationalise the act of revenge.

The Long-Term Harm of Holding On to the Urge for Revenge: Relationships and Physical and Mental Health
But did you know? Long-held resentment leads to a chronic stress response, and can bring on health problems such as anxiety and a weakened immune system (Worthington & Scherer, 2004). More ironic still, this emotion also changes the way we see the world. Once we are used to viewing things through the lens of a "victim", we unconsciously search for hidden injustice in every interaction, forming a vicious cycle that leaves us unable to break free from anger — as the proverb goes: "Resentment is like drinking poison and expecting the other person to die".
On the interpersonal level, the urge for revenge is like an invisible wall. Longitudinal studies show that people who find it hard to forgive others struggle more to feel connected to them, which can affect the harmony of close relationships and one's personal sense of well-being (Bono et al., 2007). This is because revenge, by its very nature, severs connection and blocks any possibility of repairing the relationship. At work, the person who is always determined to "get even" is easily and gradually distanced by colleagues; within the family, accumulated acts of revenge may ultimately lead to rifts that cannot be mended. When we are fixated on "demanding justice", we often miss the beautiful relationships and opportunities right in front of us, ours for the taking.
How to Overcome It? Learn to Let Go, and Let Your Soul Breathe Freely
The first step in changing the urge for revenge is to notice the vulnerability behind this emotion. When you find yourself once again replaying the "revenge script" in your mind, it is worth asking yourself: "What is it that I truly need?" More often than not, the answer is not to make the other person suffer, but a longing to be understood, to be respected, or to regain a sense of control.
In practical terms, you can try "emotional journalling" — recording in detail what happened, how you felt, and the outcome you hoped for, which helps to clear your thoughts. Another effective method is "time travel": ask yourself, "In a month's time, will I still care this much? And in a year?" This can help you shift perspective and ease the stress the emotion brings in the moment.
Most important of all is to cultivate a sense of self-worth: when you feel stable enough within, another person's offence is less likely to shake your core. You can try writing down three small things that went well each day, or regularly taking part in activities that bring you into a state of "flow" — these are all good ways to strengthen your psychological resilience.
Seek Counselling or Therapy to Set Down the Knot of Revenge
Some urges for revenge are deeply rooted, bound up with childhood trauma or long-accumulated resentment, and you can seek professional help to address the problem. Psychotherapy provides a safe space to explore the unmet needs and fears behind the impulse for revenge. One effective approach is Cognitive Behavioral Therapy (Cognitive Behavioral Therapy), which can identify and change the automatic thoughts that feed the urge for revenge; trauma therapy, meanwhile, can help repair early relational trauma and rebuild the confidence to connect with others.
TreeholeHK's Psychotherapy service (Psychotherapy) can address this kind of difficulty. A therapist will work with you to take apart those "I must take revenge" beliefs and develop healthier coping strategies. Along the way, you will come to understand that "letting go of revenge" is not "letting injustice slide", but doing it for your own peace of mind. Once you are no longer held hostage by the urge for revenge, you instead gain an emotional freedom and sense of connection you have never had before. The truly strong person is not the one who hits back hardest, but the one who is most in command of their own inner world.
