(Act5 Sc. 4 Shakespeare). In the same time his wife dies he just doesn't care and is unmoved to mourn until he has defeated his rival even though his prophecy says his downfall will happen when Birnam Forest comes to his castle, which is happening. He is still unafraid and can't process what is happening because he wants to kill so no one opposes him for his throne that he has. This to me shows that his ambition has overcome and overwhelmed Macbeth to the point of where he can no longer fell any emotions in his heart or mind.
In Shakespeare's play Macbeth, Shakespeare uses lots of tragedy in his book, which means the fall of a dignified character, and mainly concerning Macbeth. After being told he will be king by three witches Macbeth says to himself" If chance will have me king, why, chance may crown me Without my stir" (act 1 sc. 3 Shakespeare). In this he is saying that if he doesn't do anything then fate will make him king,therefore making him a dignified man. In this I think it would be true in that the king of Norway was defeated in a war that just ended the King Duncan would've made him king of Norway so that he wouldn't have to control over two countries himself. While later he turns and kills Duncan for the throne which leads to the fleeing of Malcolm, next in line for the throne, to go and get an army from Britain and kill Macbeth. While this is happening the Macbeth is becoming cruel and cold and kills all that opposes him. Before Malcolm came with his army Macbeth's wife died and he proposed" She should have died hereafter"(act5 Sc.5 Shakespeare). In this he is saying that she would've died later anyways and by saying this he has shown that his good and caring side has been defeated and his ambition doesn't care which makes him sound like a jerk and a foo that all he wanted was the throne even after his wife died.
