Why does friar laurence criticize romeo for his suicide attempt? what reasons does the friar give romeo for living? what reasons may friar laurence have for his own feelings?

Friar Laurence criticizes Romeo by telling him that he's mad and that there's no reason to behave the way he's behaving because the world is still open for opportunities. He may be saying this because he's a friar and naturally for him the world was not full of opportunities and he couldn't find true love and chase it like Romeo can.
