"My father's ghost-armed! Something's wrong. I suspect some foul play. I wish the night were here already! Until then, I have to remain calm. Bad deeds will be revealed, no matter how people try and hide them."
When should I kill Claudius and how?
One of the most common themes in Shakespears' plays is revenge. The difference between Hamlet and other works of Shakespears is that the revenge keeps getting put off.
"And you can't put your heads together and figure out why he's acting so dazed and confused, ruining his peace and quiet with such dangerous displays of lunacy?
In Act I Hamlet recieves news of the ghost lurking around and later comes to the realization that it is his dead father, King Hamlet. He is told that the ghost is armed and Hamlet automatically becomes suspicious.
"A rat! A rat!"
In Act II, Hamlet has found out that Claudius killed his father and he starts planning his revenge.
In Act III Claudius suspects that something is going on with Hamlet. Everyone believes that he's madly in love with Ophelia when in reality he's upset about his father's death and planning his revenge on Claudius.
In this scene, Hamlet is talking to Gertrude about Claudius. He then hears someone behind the tapestry and thinks it's Claudius therefore he draws his sword and stabs through the tapestry screaming "A rat! A rat!", killing Polonius who was unseen.
In Act V, Hamlet discovers that Claudius is responsible for the queen's death as well (she drinks poison from a cup that was meant for Hamlet) so Hamlet stabs Claudius with a poison sword and forces him to drink the rest of the poison that killed the queen. (Hamlet dies a little while later from the poison sword that Laertes stuck him with)
