To break into Capulet's tomb
Friar Laurence hurries to the Capulet's tomb to rescue Juliet and prevent her from harming herself after discovering Romeo dead. He plans to arrange for Juliet's protection and help her escape to a convent with the hope of eventually reuniting her with Romeo.
Friar Laurence tells the watchman that he is hurrying to get to the Capulet tomb to prevent Juliet from waking up and discovering that Romeo is dead. He instructs the watchman to go and fetch the prince and bring him to the tomb.
Because he knows Juliet is about to wake up and Romeo will not be there, since Friar John was not able to deliver his message.
Yes, After Romeo and Juliet are found in the Capulet Tomb, the Friar explains everything and the Prince punishes everyone for their contribution of hate between the families that has caused both houses death.
Two more corpses than were expected. He expected Tybalt to be there, but not Paris or Romeo. He expects Juliet to be there but she is not a corpse. Yet.

Friar Lawrence encourages Capulet to be more understanding and patient with Juliet instead of rushing her into marriage with Paris. He advises Capulet to listen to Juliet's feelings and consider her wishes before making any decisions about her future.
Friar Laurence's letter is not delivered to Romeo because Friar John was kept in quarantine since there was a plague in his house. Friar John wanted to go to Mantua himself but he couldn't. Once Friar Laurence hears this he says: "Now must I to the monument alone. Within these three hours will fair Juliet wake. She will beshrew me much that Romeo Hath had no notice of these accidents; But I will write again to Mantua, And keep her in my cell till Romeo come." His plan is to go to the tomb, get Juliet then write a second letter. But Friar Laurence's second letter is never sent to Romeo because Romeo's servant Balthazar has already told him Juliet is dead. Romeo arrives at the tomb before Friar Laurence can even write the second letter, which results in Romeo killing himself, which results in Juliet killing herself.
Friar Laurence devises a plan for Juliet to fake her own death by taking a potion that will make her appear lifeless. Juliet is initially hesitant, fearing it may not work, or that she will wake up alone in the tomb and go mad. She is also concerned about the consequences if the plan fails, such as being buried alive or waking up to find herself in the tomb with no way to communicate with Romeo.
The evidence that confirms Friar Laurence's tale is found in the letters left behind by Romeo and Juliet, which describe their love for each other and their plan to be together in death. Additionally, the bodies of Romeo and Juliet in the tomb serve as physical proof of their tragic fate.
