Different sets of images that can be used are: 1) decay and corruption; 2) descriptions of actions; 3) insanity and mental illness; 4) truth and falsehood.
Hamlet is not justified in killing Claudius until it is clear that Claudius corrupts everyone around him and that he needs to be removed for the good of the state.
Mel Gibson's portrayal of Hamlet is strong and full of life.
These considerations may affect the by which Hamlet violated moral precepts, his eligibility for forgiveness, and the extent of his punishment if called to account in a court of law.
You are a prince (princess) of Denmark.
The attempt at simple revenge, even after the positive proof of Claudius' guilt at the play, makes Hamlet, like Romeo and Laertes, subject to the law of unintended consequences.
Your father is this fabulous King who has won many victories.
But he didn't know this until the very end of the play.) So, the question is not why didn't Hamlet act, the question is why did Hamlet wait to try to take revenge a second time?
Your mother is a beautiful queen.
Just before Hamlet takes the action we've all been waiting for, the King allows Gertrude, the only person for whom he has any affection, to drink the poisoned wine.
She raised you herself and you are closer to her than to anyone.
Everyone is different and when other people are affected by our actions, there is an increased risk that we won't accurately predict how they'll react.
When you are away at school the King suddenly dies.
When Laertes discloses that Claudius is to blame for the killings, the King is revealed as an evil person who will continue to corrupt others and cause their deaths, just as he had done to Laertes and the Queen.
And then a ghost appears who looks just like your father.
Like Hamlet's attempt at revenge that led to the death of Polonius, Laertes' action is rash and poorly thought out but also taken under great provocation.
