Hamlet, a young prince of the Denmark, but without prefect life that should be admired by earthling. His father dead in sudden, and his mother re-married with his uncle who killed his father...all the thing made him involved in the tragedy life. Hamlet's tragedy is the fact that he is all words and no action, his tragic flaw being indecisiveness or cowardice. In Hamlet, the impediment to revenge is conscience whereas in its models, material considerations prevent fulfillment. In this play, procrastination is the key factor that made him lose the opportunity of the revenge for his father when the king Claudius is praying. Also, He pretends to be mad and Every time there is an opportunity to kill his uncle, Hamlet decides not to do so. His hope of the revenge for his father is strong, but when he heard the word of the ghost, he didn't do any action immediately, but became a crazy thinker. He wants his revenge prefect, and also he is a great moralizer. His negation is the crime of Claudius killed his bother, not Claudius oneself. In general, the earthling thinks if Claudius dead, the revenge is finished. But for Hamlet, he has a thought that the Claudius's body and his crime must both be destroyed. He wanted Claudius's soul should be thrown into dark hell not the heaven. One of characters of hamlet is life value prior and "to be or not to be ." And his tragedy life, one is his "to be or not to be", another is Claudius's calmly duplicity and Laertes's sensibility impulsion.
