Wrath is one of the Seven Deadly Sins from Abrahamic Lore. It is based on the emotion anger and if left uncontrolled it leads to violence, hatred, self-destructiveness and bloodthirst. It can manifest in many ways such as becoming a vigilante, revenge and being impatient. Originally, the sin also represented hatred for oneself as well as external hatred. Committing suicide is viewed ultimate expression of hatred for oneself as a result. The demon that represents this sin is either Satan, Amon or Moloch. The corresponding virtue is patience.
In Hinduism, anger is equivalent with sorrow as a form of unrequited desire. It is one of the five hindrances in Buddhism.
