Violence is an extreme form of aggression, such as assault, rape or murder.

Violence has many causes, including frustration, exposure to violent media, violence in the home or neighborhood and a tendency to see other people's actions as hostile even when they're not. Certain situations also increase the risk of aggression, such as drinking, insults and other provocations and environmental factors like heat and overcrowding.
