However, after receiving the prophecy from the witches, Macbeth's character begins to change. He becomes increasingly ambitious and driven by his desire for power. He is willing to commit acts of violence and betrayal in order to achieve his goals. Macbeth becomes tyrannical and ruthless, and his actions destroy not only himself but also the lives of those around him.
One of the defining aspects of Macbeth's character is his guilt and remorse. After murdering Duncan, he is overwhelmed with a sense of guilt and horror. He experiences night terrors, hallucinations, and other signs of emotional and psychological distress. Macbeth's internal struggles reflect the inner conflict between his desire for power and his knowledge that what he has done is morally wrong.
Despite his cruelty and ruthlessness, Macbeth is also shown to be a sympathetic character. He is tormented by his guilt and is aware of the terrible consequences of his actions. At times, he expresses regret and a desire to be free from the burden of his deeds. This complexity adds depth to his character and makes him more than just a one-dimensional villain.
In conclusion, Macbeth is a psychologically complex and well-developed character whose transformation from loyal warrior to corrupt tyrant is central to the themes and plot of the play. His descent into darkness and his struggle with guilt reflect the destructive power of ambition and greed, and leave a lasting impact on the audience.
