Macbeth's Speech Analysis

I should have been the one to confront Macbeth. I should have been able to figure out what Lady Macbeth and Macbeth did. I spent hours upon hours analyzing and scrutinizing the Lady’s strange speech from her sleep. If only I had realized it sooner, if only I had just put the pieces of the puzzle together quickly I could have been king. But no, Malcolm took over, and Malcolm got the power. But, I cannot think this way, just look at what happened to Macbeth and his wife. “Stars, hide your fires; Let not light see my black and deep desires.” But it was so obvious! The washing of her hands, her cries over the blood and her stained hands, her eagerness to hide or cover up what she had done. If only I had put the parts together I could have realized
how obvious it was that Macbeth had to be the one to kill Duncan. It just so happened that Duncan went to Macbeth’s house and was killed. If the royal guards really wanted to kill the king they would have done it earlier. But I didn't put the pieces together fast enough and I lost what little chance I could have had at power. I suppose that I never even had a chance at being king, but maybe, just maybe, people would have been so happy with me for exposing Macbeth that they would have let me take power. No. No, that would have been impossible.
