Hamlet’s false madness affects how other people view his behavior. Hamlet knew that people would write off his actions as madness over his father’s death, and he used this to his advantage. His act allowed him to essentially recreate his whole personality. It was the perfect cover for his plan to murder Claudius. In fact, acting is so important to Hamlet, he uses it throughout the play. The only time he seems that he doesn’t know how to act is when he is around Ophelia. Although this doesn’t mean that he treats her positively. Because of his actions she herself goes genuinely mad and drowns herself. Claudius is, rightfully, so utterly wracked with guilt and is so disturbed by the play, he dashes out to pray. This was a very good opportunity
