The definition of revenge is a type of justice that people of the law will not do so, regular people take it upon themselves to do it (Francis Bacon). For the story Macbeth, there are multiple accounts of this happening. Some people that this happens to is Macduff, Macbeth, and more. A good question for this play is, was revenge justified in this play or not? To answer this question, I would say yes, revenge is justified in the play when it happens. Like said previously, there are multiple people get to act upon revenge, with these different people there are many different situations that allow some of the people in the play to do horrible things or things that are justified because people of higher authority won't do anything to help or they are the ones that cause the problems.
An example of justified revenge taking place in the play is with the murder of King Duncan. Prior to this event Macbeth and Banquo are told by the witches that Macbeth will become king, and the sons of Banquo will rule after him (Third Witch, 19). Macbeth informs his wife Lady Macbeth about what happened and she wants to plan the death of King Duncan. She then encourages Macbeth to kill Duncan. When this happens, Duncan's sons, Malcolm and Donalbain flee Scotland. Malcolm goes to England while Donalbain goes to Ireland and is never mentioned in the play after that. As an act of revenge, Malcolm gets the assistants of the English king and Siward, the commander of the English forces. With them Malcolm takes the crown of Scotland where he is supposed to be. This is an example of what was stated in the story called "Of Revenge," it stated that which is past is gone...wise men have enough to do with things present and future...This means that yes;the past is gone but , it still affects what people do in the present that will affect our future.
Another example of revenge being justified is the murder of Banquo. Macbeth originally hired two people to murder Banquo ...
