Lady Macbeth is a female character who undergoes change throughout the play, as stated, and this is accurate. She is presented in the play’s opening scene as a driven and aspirational woman who will stop at nothing to support her husband’s ascension to the throne. But as the play goes on, she feels more and more guilty, and she eventually goes insane.

When Lady Macbeth reads Macbeth’s letter outlining the witches’ prophecy in Act 1, Scene 5, it serves as one of the first signs of her evolving personality. She says, “Glamis thou art, and Cawdor, and shalt be / What thou art promised” (1.5.14-15).
