Answer:
This is partly due to Hamlet's belief that there are no conclusive solutions to life's most difficult questions. Hamlet's universe is a continuous source of uncertainty.
Hamlet is suffocated by his consuming insecurities, despite the fact that those around him will and do act on their feelings. From the moment Hamlet encounters his father's ghost, and in the remainder of the play, what he is convinced of in one scene, he questions in the next. Hamlet recognizes his father's ghost on the castle wall and acknowledges its unmistakable call for vengeance. When Hamlet is alone, however, he ignores what he has seen in a whirlpool of uncertainty and terror. Hamlet is a problem play, as it represents the theme of madness. Hamlet tries to make people think he is harmless, pretending to be mad. But examining the death of his father, Hamlet is losing touch with reality. As he plans his revenge, he starts acting weird and without thinking Hamlet has the problem of procrastination and cannot act from emotions due to a lack of self-discipline. He is a man of reason and denies emotions so that his search for the truth of whether Claudius killed his father is satisfied. Shakespeare's tragic hero Hamlet's fatal flaw is his failure to act immediately to kill Claudius, his uncle and murderer of his father. His tragic flaw is 'procrastination'. His continuous awareness and doubt delays him in performing the needed "missed the mark," usually seen in his tragic flaw. In Hamlet, the Prince's tragic flaw is "indecision," in taking so long to exact revenge on Claudius for Old Hamlet's murder.
