What is the significance of Act 1, Scene ii of the play, "Macbeth"? I would like to know what is the impact of this scene on the rest of the play.

This scene is important because it shows Macbeth's characteristics before he listens to the witches' prophecies. It presents Macbeth as a brave and noble general who fights valiantly for his country, Scotland, and his king, Duncan. He seems to be loyal to the king and it seems due to Macbeth's actions in the battlefield, he is going to be rewarded by the title of Thane of Cawdor - since the original incumbent turns out to be a traitor.

With reference to the whole play of "Macbeth", this scene is very important because it shows what Macbeth's character is like before its deterioration started. Also, it highlights the atrociousness of Macbeth's murder of Duncan. It is also important to the plot of the play because it shows the normal order of society before the disorder starts, which, in tragedies, is solved through the death of a person. In this one scene we get the idea of the positions of most of the major characters in the society so that we can understand what starts to go wrong from the next scene.
