Where is an example of moderation in Act 3 of "Romeo and Juliet"?
In Act III, scene I, Tybalt challenges Romeo, saying
Boy, this shall not excuse the injuries/That thou hast done me; therefore turn and draw(ll.54-55)
However, since Romeo has married Juliet, he is now related by marriage to Tybalt. Consequently, Romeo tries to ameliorate feelings between him and Tybalt since they are now related by marriage:
I do protest, I never injured thee,/But love thee better than thou cast devise,/Till thou shalt know the reason of my love:/And so, good Capulet,--which name I tender/As dearly as mine own,--be satisfied (ll.56-60)
At these words Mercutio is incensed and accuses of Tybalt wanting to walk away from a fight. Still Romeo tries to avert a fight and begs his friend, "Gentle Mercutio, put thy rapier up" (l. 70 ). Then, he entreats Benvolio to stop Mercutio and Tybalt, crying out,
Gentlemen, for shame, forbear this outrage!?Tybalt, Mercutio, the Prince expressly hath/Forbid bandying in Verona streets:/Hold, Tybalt! good Mercutio!(ll.72-76)
Of course, Romeo's attempts, though well-meaning, fail.
