Abstract
"Ambition is the step that can turn a noble-hearted man into a sinner" is the message Shakespeare wanted to convey to the audience when he wrote the play Macbeth in 1606. Lady Macbeth's is the wife of an important nobleman: Macbeth, they are both characterized by their great ambition of becoming king and queen. Although she is a woman, her character is very important in the play because Lady Macbeth has a stronger personality than her husband, she knows how to manipulate him to obtain the death of the king and therefore the power she is longing for. Macbeth, obsessed and paranoid by his desire to be king, decides to murder Duncan. He betrays the cause he had been serving by committing several other murders without Lady Macbeth's encouragement, which will lead both of them to death: he will be killed by Macduff's sword and she will commit suicide, haunted by guilt.
