Revenge spirits are manifestations of unfulfilled anger and vengeance from the afterlife. Often born from untimely deaths or deep betrayals, these spirits linger in the mortal world to seek retribution. They haunt individuals or places tied to their grievances, often causing fear, misfortune, and even death to their targets.
These spirits are common across cultures, symbolizing the unresolved emotional and moral debts of the living. Their presence in folklore serves as a stark reminder of the consequences of injustice and neglect, urging humanity to honor and remember the dead while seeking resolution in life.
