After killing Tybalt, Romeo goes to Friar Laurence for help. How is immaturity evident in Scene 3, and do you believe the Friar's scolding changes Romeo?

Immaturity is evident in this scene, as Romeo, lacking gratefulness for a punishment of banishment over death, carries on over the separation it will require from Juliet. Romeo weeps and laments his situation, focusing only on himself. He even goes so far as to threaten suicide by stabbing himself. I see no evidence that the Friar's scolding or advice has any effect on Romeo whatsoever.
