It'd be helpful if you also named his Nemisis, Agnarosis and Catharsis. This is so I get a better understanding of what Romeo really was to Shakespeare.
Shakespeare aligns Romeo with the classical archetype of the tragic hero who accepts his terrible fate head on. Much in the way that the characters in Richard III dream about their fates in the final act of that play, Romeo also has a dream which foretells his fate. He says, "I dreamt my lady came and found me dead" (5.1.6). The dream both foreshadows the ending and suggests that greater forces – perhaps the “plague” that Mercutio tried to bring forth – have come together to ensure a tragic ending.
The events of Act 5 do not provide a clear answer to the question of whether Romeo and Juliet is a tragedy of fate. Instead, one could continue to argue that the tragic ending is the result of individual decisions - most notably, Friar Laurence's complicated plan. The success of this plan is highly contingent on timing and circumstance. What if Friar John had not been waylaid? What if Romeo had arrived at the Capulet tomb two hours later, or if Friar Laurence had arrived one hour earlier? Fate is not typically so contingent on human actions, which suggests that the most powerful force at work in Romeo and Juliet is actually the psychology of the characters. The uncertainty in these final scenes makes the play less classically tragic and yet more unique for not being fully aligned any one form.
