Violence leads to more violence

In the book Julius Caesar, there was a similar situation of violence lead to more violence.
When Brutus and other conspirators killed Caesar, Antony, and Octavius fought against them. Also all the citizens, after the speech of Antony, got upset and started to go against Brutus and Cassius. So the first violence was when the conspirator stabbed Caesar, and it lead to a bigger violence which resulted as a war between the conspirators and Antony and Octavius. nowadays i think it is more less, because you can't really go to war that easily. but one of the examples will be when there are normal citizens uprising or protesting against the government, then the government will try to stop by adding more army or police support to the city, and there would be a bigger and more violence between people and the government.
