The most important subjects in the tragedy of Romeo and Juliet is that of choice. There is ample evidence of both fate and free will in the play, and the presence of both greatly affects the interpretation of the plot and the characters.
Fate as a dominating force is evident from the very beginning of the play. The Chorus introduces the power of fortune in the opening prologue when we are told that Romeo and Juliet are “star-crossed” (destined for bad luck) and “death-marked,” and that their death will end their parents’ feud. By telling us that Romeo and Juliet are destined to die because of their bad luck, Shakespeare gives us the climax of the play before it even begins.
The characters themselves all believe that their lives are controlled by destiny and luck, and Romeo is a prime example of this. When Romeo and his friends journey to the Capulet’s ball in Act I, scene iv, Romeo hesitates to go because he has had a bad dream.
Romeo’s belief in fate also affects his interpretation of events. When Romeo kills Tybalt in Act III, scene i, he claims that he is “fortune’s fool” by having contributed to his own downfall. “Is it e’en so? Then I defy you, stars! / Thou knowest my lodging” (V, i. 24). Romeo finally tries to escape from his destiny at the end of the play by committing suicide to “shake the yoke of inauspicious stars,” ironically fulfilling the destiny declared by the Chorus in the opening prologue.
