MacBeth had a lot of problems and conflicts during his reign. Although some were worse than others, they all brought him to his downfall. Internally MacBeth had to deal with his conscience, he had to live with what he had done to Duncan. At first what MacBeth had done really was eating away at him, but once he became King, he grew into it and it didn't bother him anymore. Lady MacBeth and MacBeth were complete opposites when it came to this matter, because Lady MacBeth was really bothered by it after a while.
             I think the early signs that shows that MacBeth was worried was when he kept saying "amen" when Duncan's body was found.

This to me was MacBeth's first mistake and one that he would pay for.
             I think that another external conflict was his wife. Lady MacBeth drove MacBeth to do things that he really didn't want to do. He didn't want to become king as bad as he thought he did, but his wife filled his head with how good it would be for them. Lady ...
