In Shakespeare's Romeo and Juliet, Friar Lawrence's plan is unlikely to succeed as is proved in the play. When it comes to convincing Juliet's family of her pretentious death, it has to be realistic. Her fake death plan had to be kept a secret. For this reason, Romeo does not get word that Juliet is only sleeping. Friar Lawrence's plan does not work. Romeo does not get the message from Friar Lawrence in time. Before following through with such a strategically serious plan, Friar Lawrence should have made sure Romeo was aware of the pretentious death plan of Juliet.
Romeo left town while awaiting Friar Lawrence's original plan to talk to both the Capulets and Montagues. Romeo did not know about Friar Lawrence's sleeping potion plan. When Friar Lawrence made a change in plans, Romeo had not been advised. For this reason, Friar Lawrence should not have followed through with the plan. When all parties involved do not have sufficient instructions on how the plan will unfold, the plan is likely to fail and that is exactly what happened:
The friar's plan fails, mostly due to accidents of mistiming. Romeo receives word of Juliet's "death" through his servant. The friar's news that Juliet is not actually dead has been prevented from getting through to Romeo.
When Romeo gets to the tomb, he thinks Juliet is dead and he kills himself. Juliet awakens to find her beloved Romeo dead. Friar Lawrence gets to the tomb and "tries to persuade her to leave."
Juliet stabs herself with Romeo's dagger. She would rather die than to live without Romeo. No doubt, Juliet's love is so deep until she cannot exist without the love of her life.
Truly, Friar Lawrence did not prove to be helpful enough. Of course, he was only trying to find a way for the two young lovers to be together. In the end, his plan failed. Nevertheless, the Prince does not blame Friar Lawrence. Instead, he blames the feuding of the Capulets and Montagues for the deaths of their children.
