Tybalt and Mercutio were similar in many ways, one of which is that they were both hot heads looking for a fight. So one could read the scene as two equally matched young men whose fates would be determined by which man was faster or better skilled. Tybalt probably did not want to kill Mercutio. He really was after Romeo. And surely Romeo did not want to be responsible for pushing Mercutio to the point where Mercutio would die.
These were the circumstances surrounding the fight between Tybalt and Mercutio. The question of who was responsible, however, appears to have one element missing. What about Mercutio himself? Where does his responsiblity in this affair come into play? Are we not responsible for our own actions? No one forced Mercutio to take action. He did so of his own free will. Did he feel that he had to protect Romeo or to save his own honor? Maybe. But he and he alone made the decision to pull out his sword and go on the attack. Was he crazed at the moment? Possibly. But this does not diminish his responbility. At some point, Mercutio made a decision, and from that point, circumstances played against him and he was forced to face his death.
Tybalt kills Mercutio, but it is Romeo who was challenged by Tybalt but refused to fight. Then, at the moment of death, Romeo's interference helps seal Mercutio's fate.
However, Tybalt is the one who kills Mercutio and it is he who challenges Romeo in the first place.
Tybalt kills Mercutio.
I honestly don't know who Shakespeare intended the one to blame be. There's lots of choices to chose from. My brother is doing a paper on who is to blame in act 3. He asked me my opinion and I really didn't know. I got all into the book and thought about it for days until finally I came up with a solution. At first everyone thought in his class it was mercurtio because he is always starting trouble. But this time Tybalt is the one to blame because hes the one who asked Romeo to duel with him. Romeo backed down which led to mercurtio fighting Tybalt which leads to Romeo killing tybalt. Which leads to juliet.
I also think that romeo took part in this too in act 3 because if he didn't back down to the fight merCurtio Tybalt woulsnt have called him.
Both of em. Tybalt did the actual stabbing while Romeo intervened.
tybalt was responsible for mercutio's death
