Answer:
The tragic deaths of Romeo and Juliet can be attributed to one person: Friar Lawrence. Friar Lawrence is to blame for the deaths of both Romeo and Juliet because he masterminded their plan to fake Juliet's death and violated his own oath as a member of the clergy. He was willing to go against the chief authority in society, the Prince, and betray his own sense of morality in order to bring about a reconciliation between the two families.
The first piece of evidence supporting the blame of Friar Lawrence is his involvement in crafting a dangerous plan to reunite Romeo and Juliet. He suggested that Juliet take a potion that would make her appear dead in order to avoid marrying Paris and reunite with Romeo instead. The effects of the potion could not be accurately predicted and if Romeo had received the letter informing him earlier, it may have been possible to save Juliet’s life. This alone demonstrates Friar Lawrence’s reckless disregard for the safety of Romeo and Juliet.
Second, Friar Lawrence broke his oath as a religious man when he married Romeo and Juliet without obtaining permission from the parents. Moreover, despite knowing the deep enmity between the Capulet and Montague family, he still shared his plan with the couple instead of talking them out of it. His disregard for the law and his authority implies that he was more concerned about the two families being reunited than the well-being of Romeo and Juliet.
Finally, Friar Lawrence failed to recognize the fragility of young romance and betrayal. Both Romeo and Juliet were deeply in love, but desperate and vulnerable in the face of their families' antagonism and rigid authority. Friar Lawrence was aware of this, yet still encouraged the two to go through with the dangerous plan, thereby not only worsening the situation but also taking advantage of their naivety and innocence.
Overall, it is clear that Friar Lawrence played a large role in the untimely deaths of Romeo and Juliet. He masterminded an ill-conceived plan, violated his own oath, and failed to protect the two young lovers. In doing so, he was ultimately responsible for Romeo and Juliet’s demise.
