Unchecked Ambition In Macbeth

When Macbeth says, "Things bad begun make strong themselves by ill.", he is talking about the murders and the lies he has to keep up with. "Things bad begun" means that he started off doing wrong when he committed the first murder. "make themselves strong by ill." means that once he continued on murder to maintain the crown things had only gotten worse, and he started to lose his mind with all the guilt he had to live with. A major theme in Macbeth is unchecked ambition, or a strong drive for success that can't be controlled. This theme represents a comment on life because most of us are all caught up on what we want ourselves to become, we would be willing to manipulate other to get to the top.
