Conversely to the actions of Gertrude and Polonius, Claudius’ intents are malicious. Regardless of the differences in intentions, Hamlet’s insanity and tragic death can be attributed to the things Claudius does. First and foremost, Claudius murders old king Hamlet and assumes his position on the throne. Hamlet finds out about this when the ghost recounts “Thus was I, sleeping, by a brother’s hand of life, of crown, of queen and of despatch’d” (I . V . 75-76). Hamlet displays his first acts of insanity when he calls Horatio and Marcellus saying “Hillo, ho, ho, boy! come, bird, come.” (I . V . 117). This is evidence for Hamlet’s negative mental shift as a consequence of Claudius’ murder. Later on, Claudius plans to have Hamlet executed in England.
