Throughout Hamlet, by William Shakespeare, the main character (Hamlet) refuses to let go of the belief that his uncle killed his father so he could marry his mother. He only happens to believe this because at the beginning of the book his fathers ghost comes to him to tell him about the horrible crime and how to get revenge on this unspeakable human being. He carries on with this belief through the story, although toward the end the specific consequences for his actions will come into play.
Firstly, he holds a play and asks the actors to reenact his uncle murdering his father just so he could see Claudius’s response. Seeing that his response was to leave the room and make details to send him to England, Hamlet is indeed correct in the details of the crime. Secondly, Hamlet is so strung out on killing his uncle that when he goes to speak to his mother, the Queen, there is a noise behind her curtain and Hamlet automatically assumes Claudius is eavesdropping. Immediately, he stabs Polonius through the curtain and he dies. This is consequence number one.
The next consequence is Ophelia. Hamlet acts to crazy toward her that she eventually drowns herself to get rid of the pain.
Next, Claudius talks Laertes into a fencing match with Hamlet. The plan was to kill Hamlet by taking the stopper off of the tip of Laertes sword and put poison on it and also if that didn’t work they were to put the poison in Hamlets water so he would drink it and die, either way. In the end, everyone else dies as a consequence.
