An individuals power depends on the person them self. Power is not something you are born with; you must want it and gain it. Power is depended upon the surroundings you are in and the people you are with. At first, Macbeth didn't want power enough to make sure he got what he wanted. I on the other hand, being the perfect wife I am, helped Macbeth make a decision to become a powerful being. I taught him that power is not handed to you. You must take control of it. Duncan was in the way of Macbeth gaining power so, being the smart women I am, I made Macbeth kill him to ensure that he really wanted all this power. Macbeth DID become king, right? I know, I know. I am just so smart!:)
