Hamlet
One of humanity's most basic instincts is that of revenge. Revenge is one of the defining traits of humanity. The drive to exact vengeance on one's enemy is the driving force behind many pivotal events in human history. The object of every war is to get revenge on the other side.

However, revenge is by no means a perfect deterrent. This is especially clear in Shakespeare's Hamlet. Take Claudius, for example. He could not conceivably have thought that Hamlet would not
