A murderer and a villain;
A slave that is not twentieth part the tithe
Of your precedent lord; a vice of kings;
A cutpurse of the empire and the rule,
That from a shelf the precious diadem stole,
And put it in his pocket!
– William Shakespeare
Hamlet, Act 3, Scene 4. Hamlet unmasks Claudius to Gertrude as a murderer who stole the crown and kingdom and is not worth a fraction of her previous husband. He is trying to torture his mother with guilt.
