Hamlet's tale is a tragic one because it presents a man who is in the center of a moral dilemma. It is difficult enough for a man to face what is making him angry even under normal circumstances. Hamlet's circumstances are certainly not normal.
Hamlet's dilemma, whether or not he should kill the king, is compounded by three things. He is extremely angry and hurt over the murder of his father.

Hamlet (correctly) blames his uncle, Claudius, for the death of his father. Further compounding the issue is the fact that Claudius is now the King of Denmark and is married to Hamlet's mother, Gertrude.

This would only anger Hamlet even more since he feels that he would get caught for his 'justifiable homicide' and Claudius did not get caught for his crime. All Hamlet can do is keep quiet, and that only makes him even...
