How do the friar's motives differ from the couples motives?

The friar's motives in Romeo and Juliet are driven by a desire to bring about peace and reconciliation between the feuding families. On the other hand, the couples' motives, particularly Romeo and Juliet, are fueled by their passionate love for each other, regardless of the ancient grudge between their families. The friar seeks to resolve conflict, while the couple is focused on their personal relationship.
