Answer:
Lady Macbeth is a complex and multi-dimensional character whose psychological journey is a testament to the devastating consequences of unchecked ambition. As her husband engages in the acts of violence required for the fulfillment of their ambitions, Lady Macbeth’s conscience begins to falter, and her sense of moral responsibility increases. In Act II, Scene II, Lady Macbeth celebrates the success of her plans and encourages Macbeth by suggesting that their deed can easily be cleansed with a little water. Her statement reflects her initial lack of morality and guilt which has been overshadowed by ambition. However, as the play progresses, Lady Macbeth begins to experience guilt and remorse which is evident in her sleepwalking and her desperate attempts at cleansing her hands. By Act V, Scene I, Lady Macbeth is so consumed with guilt that she is unable to find peace, suggesting that unchecked ambition almost always results in regret and despair. This supports the theme emphasized throughout the play that the consequences of unchecked ambition can be catastrophic.
