Revenge

"Speak; I am bound to hear." It is Hamlet's duty as a son to listen to his father, ghost or not. Hamlet is told it is up to him to avenge his father. His father's life was taken by Hamlet's uncle and Hamlet vows to prove his love and loyalty by taking revenge on his uncle.

REVENGE

" 'the croaking raven doth bellow for revenge"

"Revenge his foul and most unnatural murder"

...spur my dull revenge!

Hamlet isn't the only one with an agenda for revenge. Look out for Laertes...

"My revenge will come"

For you dad...
