In the play "Macbeth" written by the playwright William Shakespeare, the development of the idea of excessive ambition leads to downfall and how power corrupts is used to show how being too ambitious can only lead to bad things in life. People of the Elizabethan times would have thought that excess in ambition would only do you wrong, whereas nowadays, people believe the more ambitious you are, the greater you will become. This is developed through Macbeth, as at the start he is a well-respected noble, but when his want for power corrupts him, it leads to the destruction of himself.
In the play "Macbeth" many people are portrayed to have personalities that are ready to beg, borrow, steal, and even kill to obtain certain levels of power to soothe his or her ambitions. Macbeth, himself, is one of these people – this is shown when he is willing to kill King Duncan after the Witches tell him that he shall become king after Duncan dies. Macbeth's want for power overbears his will to stay good, and we see this from the dialogue he uses when he is fighting with himself over whether or not to kill the king. "I have no spur/To prick the sides of my intent, but only/Vaulting ambition, which o'erleaps itself,/And falls on th' other" We later see that this statement he uses is true, and that Macbeth's ambition for power makes him corrupt and does indeed bring about his own downfall.
