Juliet undergoes a significant transformation throughout the play as she transitions from a sheltered and obedient girl to a strong and independent woman. Initially, she accepts her parents' authority and complies with their wishes for her to marry Paris, even though she does not love him. However, when she meets Romeo at the Capulet ball, she experiences a newfound sense of freedom and begins to pursue her own desires. She defies her family and societal expectations by secretly marrying Romeo and later taking drastic measures to be with him, such as faking her own death.
As the play progresses, Juliet's transformation continues to unfold. She becomes more assertive and vocal about her own wishes and desires, particularly in her interactions with her parents. She defies their authority and refuses to marry Paris, even at the risk of being disowned by her family. Juliet also displays remarkable bravery and determination, particularly in her decision to take the potion that Friar Lawrence gives her in order to avoid marrying Paris.
Ultimately, Juliet's transformation is complete when she chooses to take her own life rather than live without Romeo. In this final act, she shows incredible courage and selflessness, as she puts her love for Romeo above everything else, even her own life. Juliet's journey from a submissive daughter to a strong and independent woman is a central theme of the play, and it highlights the power of love to transform individuals and challenge societal norms.
