The third act is the most important in the solution of the problem. Hamlet does the correct thing to be sure that his uncle actually did kill his father the late king Hamlet. Because of the play, Hamlet was able to determine whether his uncle the new king was actually guilty or not without confronting him. We all agree that in situations like this one it is very complicated to do the right thing, but he tried to search for a solution in a way that he didn't have to involve himself in the problem. Also the story is trying to give us mixed feelings with Hamlet, making us question on whether he has actually gone mad or not. Not only did he kill a man without any hesitation but we were showed that Hamlet is the only character that can see the ghost of his dead father.
