Hamlet is a story of a young prince who learns of his father's murder and seeks to enact revenge on his murderous uncle. Hamlet is full of hatred for his uncle's devious acts and disgust for his mother's sexuality. Hamlet has a group of actors perform a scene closely resembling the way by which he imagines his uncle to have murdered his father. Hamlet believes that if Claudius is guilty, he will surely react. Hamlet is not perfect, and his misfortune is not wholly deserved, but his tragic fall is not a complete loss.
Hamlet is a man of noble stature; although he is preeminently great, he is not perfect. Hamlet is thoughtful and contemplative. He must find absolute proof that Claudius killed his father. Hamlet behaves impulsively and makes rash decisions. For a man thought to be faking insanity, Prince Hamlet seems to have very little control of his emotions. In fact, Hamlet admits this to his close friend Horatio, when he says, "Sir, in my heart there was a kind of fighting / That would not let me sleep" (5.2. 4-5). This lack of restraint leads to Hamlet's unpredictable mood swings throughout the play. Hamlet is extremely melancholy. He is upset because of his mother's hasty marriage to his uncle. At one time he believed in his mother's purity and goodness, but eventually Hamlet seems to hold a great mount of contempt for Gertrude, especially when he mocks her words, and then snidely proclaims: "You are the queen, your husband's brother's wife, / And would it were not so, you are my mother" (3.4. 15-16). Such mood swings as these definitely prove that Hamlet could not keep adequate control of his emotions. .
Hamlet's downfall, therefore, is partially his own fault; nevertheless, his misfortune is not wholly deserved. Hamlet is a man who can be impulsive and dangerous. The lack of discipline leads Hamlet to shamelessly stab Polonius behind a curtain without knowing for certain who he is; Hamlet thought he was stabbing Claudius behind the curtain.
