Macduff comes in with Macbeth's head as his trophy. They successfully took over the castle. Malcolm is crowned king and he declares that all thanes will be made earls.
I assumed either Macduff or Malcolm would in the end become king. Macbeth should have never been king in the first place. The power got to his head and ruined him. In the beginning of the story Macbeth seemed to be a good guy, the power and witch prophecy ruined him and his wife. Malcolm was always the rightful king to the thrown, If he hadn't run away maybe this whole situation and all the deaths could have been avoided. But then Shakespeare wouldn't have a story. I think Malcolm will make a great king, like his father. There bravery saved Scotland from Macbeths evil rein. Macbeths death was a sweet relief for the Country and for himself. His blood lust and killing had consumed him, he had lost his mind. His death although gruesome brought him peace.
