The Turning of Fate

What I found most interesting about Act V is the way that the way Macbeth was so confident in fate began to hurt him. Earlier in the play, being confident in what the weird sisters said seemed logical, and Macbeth's flaw was pursuing this prophesy while ignoring the second half. Now, however, after hearing the weird sisters say he will only be threatened when Dunsinane Hill moves and by a man not born of woman, his flaw is being so sure that these things are not going to happen and trusting in fate instead of himself. Perhaps if he was a better king and did not trust in these prophesies he could have saved himself, but instead he takes it for granted that he will never be killed. On the other hand, the approaching English army is much more cautious. They say things like: I hope that this day is victorious, while Macbeth calls his assistants fools for even beginning to fear that they will lose. The most important theme of Act V seems to be that one can never rely on fate unfolding a certain way.
