Violence leads to more violence

Here are a couple of examples showoing how violence leads to violence:

• Once the mental violence or hatred for Caesar had begun in Cassius' mind the real violence took place when the conspirators killed Caesar. Then the speech that Antony gave made even more violence since the plebians killed a helpless poet because he had the same name as a conspirators. Finally a war sprung out and even more violence had begun.
• Really any war, begins with one group attacking another. Since the other group wants revenge, they attack, and soon enough a whole war is started.
• At my house, my friend always picks on and teases this other guy. Soon enough this guy gets really mad and tries to beat up the guy who teases him. Although he doesn't succeed, it is still a situation which does show violence creating more violence.

This is a sad truth but a true statement anyway.
