does violence lead to more violence?

Violence defiantly leads to more violence, its like a cycle. An example from the real world is Iraq attacking the U.S and then the U.S wanting revenge so they go and attack Iraq. One example from the book Julius Caesar is when Cassius and the other conspirators kill Julius Caesar, then Antony and Octavius want revenge, so they seek to Cassius and the other conspirators. Like i said violence leads only to more violence.
