Part one --

In Act 3 Scene 1 who is really responsible for Mercutio’s death: Mercutio, who provoked the fight, Tybalt who stabbed him, or Romeo who got between them? Use specific evidence (direct quotes) from the play to back this up. 
In my opinion, Mercutio should be responsible for his own death. Because in the Act 3 Scene 1 he kept trying to provoke Tybalt. "And but one word with one of us? Couple it with something, make it a word and a blow." This quote was directly spoken after Tybalt said to Mercutio and Venvolio that he wanted to talk with Romeo. He wanted to fight with Tybalt but Tybalt did not want to have struggle with him. When Romeo came And met Tybalt, he wanted to solve the problem peacefully; while Tybalt wanted to fight with him. At that moment, Mercutio could not control himself. "O calm, dishonorable, vile submission! Alla stoccato carries it away." He thought it was a shame to solve the problem between Capulets and Montagues peacefully; so he took out sword and fought with Tybalt. During the fight, Romeo tried to stop them, but suddenly, Tybalt stabbed Mercutio. If Mercutio could understand Romeo wanted to solve the problem peacefully because Tybalt was his cousin in law, he would not die.

How would you stage this as a director? Be specific.
When Mercutio and Benvolio talked before Tybalt came in, they should talked about how brave they were, and what would they do if they met Capulets. When Tybalt came, rather than having argument with Mercutio, he should be patient and have a good tempered until Romeo came. When Romeo came in, Tybalt should show the emotion of anger and voice should be louder, while Romeo's words should be soft  in order to show that Romeo did not want to fight. Mercutio at this time should be impatient, and described Romeo as a coward and took out his sword to fight with Tybalt. When they are fighting, the music should be a fast tempo music piece and it should show the anger between both Tybalt and Mercutio. After Tybalt stabbed Mercutio and flew away, Mercutio should be a little bit crazy, and yelled out  its all the fault of these two familes.  Then, Romeo got furious and fought with Tybalt. He should stabbed Tybalt really hard.
