Macbeth feels that he is living a charmed life now that he king of Scotland and that no harm will come to him because the witches gave him a second set of prophecies that basically said beware Macduff, the Thane of Fife, no man of woman-born shall harm him, and don’t worry until Great Birnam Wood come to Dunsinane. Macbeth does not fully understand the implications of these prophesies, and he only takes the first one to heart causing him to be overconfident. Macbeth thinks that getting rid of Macduff will solve his problems since he figures that everyone has been born from a woman and that the forest cannot move to come to his castle.
