Macbeth is portrayed as being a loyal and noble man but when faced with a life-changing decision, his dark side begins to surface and greed takes over common sense. He appears to be quite gullible and is persuaded easily by his wife and the witches into becoming king and letting nothing get in the way.
After a Macbeth returns from a battle, he is seen to be “noble Macbeth” in the eyes of King Duncan. By the end of Act 1 Scene 3, all seems to be going smoothly in Scotland: battles have been rewarded and good fortune prophesised without Macbeth having to do much at all. “If chance will have me king, why chance may crown me without my stir”. But from the beginning, we are shown a great man that is stained with evil and when Duncan announces that Malcolm would be the next in line to the throne, Macbeth sees red, and now the idea of killing his way to the throne is imbedded in his mind.

Duncan is family and the King, which gives him all the more reason not to follow through with it.
When his wife enters, hoping for him to go through with it, he delivers his decision: “We will proceed no further in this business”. But she sees this as a chance. Macbeth is respected by Duncan and many people now ‘believe’ he is a good person. She understands Macbeth well and knows of his sense of honour and that she fears will stand in the way of their desire for the throne.
