Revenge is when someone does something bad back. 
Revenge is doing something bad back to someone. 
In some places, this can last a long time. It can become a cycle between families. This is sometimes called a feud.
Even animals can seek revenge. Some chimps and crows do this too. It is a way to show power. It is interesting to see how many living things act this way.
Revenge is when someone does something harmful to another person. This happens because of a real or felt wrong. 

Philosophers say revenge is not the same as punishment. Punishment aims to stop future wrongs. Revenge is driven by anger and a wish to see someone suffer. People often disagree on if an act is revenge. It is often just a label that others give to an act. 
Many animals also seek revenge. Chimpanzees do this to show dominance. Crows can even carry feuds like humans do. Even fish have shown this behavior in studies. It is a common trait in many living things.
Revenge is an action meant to cause harm to a person or a group. This happens because of a grievance, which is a feeling that something wrong was done. 

In some societies, revenge can turn into a long cycle called a feud. A feud is a series of fights between families or tribes. These cycles often happen because people want to protect their honor. When a group feels insulted, they might retaliate to restore their dignity. This can create an endless loop that lasts for many generations. In Albania, this tradition is known as gjakmarrja, or blood feuds. These feuds can involve extended relatives rather than just one person. Similar traditions have been found in parts of Turkey and Papua New Guinea.
History shows us many different ways people have viewed these actions. In Japan, the practice of revenge killings was called katakiuchi. This often involved a person's relatives as well. 
Revenge is also a very common theme in art and stories. You can find it in famous paintings and many different operas. In literature, authors like William Shakespeare used it in plays like Hamlet. Some stories use a device called dramatic irony to build tension. This is when the reader knows something that the characters do not. There are even famous sayings about revenge. One popular English phrase is that revenge is a dish best served cold. This suggests that revenge feels more satisfying if it is unexpected.
Interestingly, humans are not the only ones who act this way. Many animals have been seen seeking revenge in the wild. Primatologists have studied chimpanzees and seen them use revenge to gain dominance. Even birds like crows can carry feuds similar to human ones. Professor John Marzluff has studied how crows behave in these ways. Some studies even show that fish can display vengeful behavior. It seems that the desire to react to a wrong is found in many living things.
Revenge is defined as committing a harmful action against a person or group. This action is a response to a grievance. A grievance can be a real injury or a perceived one. 
Social psychologists study why people seek revenge. Ian McKee states that the desire for power motivates vengeful behavior. People use it for impression management to protect their status. They do not want to lose face or authority. In many societies, revenge is tied to the concept of honor. An avenger may feel they are restoring a lost dignity. Michael Ignatieff describes it as a desire to honor the memory of the dead. This can turn honor into a heritage that passes through generations.
When honor is compromised, it can trigger a cycle of retaliation. This cycle can involve entire communities or families. These long-term cycles are known as feuds. Feuds are patterns of provocation and retaliation between groups. They were common in pre-industrial societies, especially in the Mediterranean. In Albania, this is known as gjakmarrja, or blood feuds. These feuds can last for many generations. Similar traditions exist in Kurdish regions of Turkey and Papua New Guinea. 
Different cultures have specific names for these practices. In Japan, revenge killings were called katakiuchi. These acts could involve the relatives of an offender. Today, katakiuchi is mostly pursued through peaceful means. History also shows the distinction between punishment and revenge. Philosophers argue that punishment is a rational act for the future. It aims to prevent wrongdoing from being repeated. Revenge, however, is motivated by a desire to see a transgressor suffer. It is driven by anger rather than logic.
Psychologists note that revenge is often an inference. There is no objective standard to declare an act as revenge. It is a label that observers assign to an action. Some people also experience the just-world fallacy. This belief can increase distress and motivate a search for justice. Research shows that a vengeful disposition can affect health. Strong desires for revenge correlate with post-traumatic stress disorder symptoms. It can also be linked to psychiatric morbidity.
Revenge is a massive theme in art and literature. In literature, authors use it to create tension. Many stories use dramatic irony to do this. This is when the audience knows more than the characters. Common themes in revenge stories include disguise and secrecy. They may also include power, violence, or even cannibalism. Famous examples include Shakespeare's Hamlet and Dumas's The Count of Monte Cristo. Even modern novels like Gone Girl use these themes.
In the modern age, the internet has created new ways to seek revenge. Consumers may target businesses with negative online reviews. This can cause significant damage to a corporation's reputation. Social media platforms also allow for new forms of public retaliation. One harmful example is revenge porn. This involves sharing intimate images to cause shame and humiliation. This behavior often relies on the anonymity provided by the internet. It is a digital version of seeking to harm another's reputation.
Humans are not the only species that exhibit vengeful behavior. Primatologists like Frans de Waal have studied this in primates. Chimpanzees often use revenge to seek dominance. If one chimpanzee helps another defeat an opponent, the opponent may retaliate later. Other animals like lions, elephants, and crows also show these patterns. Professor John Marzluff has studied crows that carry feuds. Even fish have been observed to demonstrate vengeful actions. This suggests the drive for revenge is found across many different species.
