In "Romeo and Juliet", is Friar Lawrence wise to agree to marry Romeo and Juliet? Explain.

In his own mind, Friar Lawrence is wise to marry Romeo and Juliet because he thinks that the marriage will unite the two families and will bring peace to the town of Verona.  In reality it was an unwise and a not very well though out plan to marry the two teenagers.  In marrying them, he shared a common trait with both Romeo and Juliet -- he rushed into a decision and did not really think about the repercussions of what was about to be done.  Friar Lawrence's decision brought about the deaths of Paris, Romeo, Juliet, Lady Montague, and possibly even the deaths of Tyblat and Mercutio.
