Macbeth kills Duncan to become King because the witches have told him he will be king. It is a man vs. man conflict because he argues with himself over what he should do.
Macbeth kills Banquo and also Macduff's family who are thought to be danger by the Weird Sisters.
Macbeth realizes that all the things that the sisters told him were false because Macduff was born by a C-section meaning that he was not safe as the King anymore. Also the tree's were moving and there was a big battle between Macbeth and Macduff.
