Benvolio wanted to stop the fighting and prevent any further violence between Romeo and Tybalt. He tried to intervene and keep the peace, but Tybalt was determined to fight.
Benvolio and Tybalt was there at the scene with Romeo when Mercutio was stabbed; then died.
A number of people do at various times. Benvolio does by trying to stop the fight in Act 1 and also the fight between Tybalt and Mercutio. So does Romeo. Friar Lawrence does by thinking that marrying Romeo and Juliet will end the feud. The Prince does by banning street fights on pain of death. Even Capulet does by telling Tybalt to lay off Romeo at the party.
To them its just a hobby or a sport until it leads to death were Tybalt kills Mercutio and later Romeo kills Tybalt.
Benvolio
because in the previous scene,romeo was married to Juliet and that made Tybalt Romeo's cousin.he thought wrongly of fighting him.
The answer to your question depends greatly on which scene you're talking about. For now I'll assume you mean the scene in which Romeo kills Tybalt. This is Act III Scene I.This is the first scene after Romeo weds Juliet. Tybalt is actually Juliet's cousin, so when Romeo refuses to fight Tybalt ("Tybalt, the reason that I have to love thee/ Doth much excuse the appertaining rage/ To such a greeting. Villian I am none./ Therefore farewell. I see thou knowest me not." --Romeo, Act III, scene i.), Romeo's friend Mercutio fights Tybalt instead, and in the end Mercutio dies.Romeo is furious. He challenges Tybalt and kills him, which leads to Romeo's banishment.Of interesting note is that this scene is actually the climax of the play.In performance, the scene opens with Benvolio and Mercutio onstage. Tybalt joins them, looking for Romeo. Romeo then arrives, and the fight between Tybalt and Mercutio takes place onstage. When Mercutio is wounded, Tybalt flees, and Benvolio helps a cursing Mercutio offstage. He returns shortly with the news that Mercutio is dead. It is at this point that Tybalt "returns to the scene" as the question asks. Romeo then explodes at him, telling him that Mercutio's spirit is just overhead and "either you or I or both must go with him." Then follows the fight between Romeo and Tybalt.
It doesn't say anything about Romeo's cousin, but many people mistakenly think Benvolio is. Benvolio is just his friend. Benvolio is the Prince's cousin. Sorry, that's wrong. Benvolio is Romeo's cousin. In Act 1 Scene 1 Benvolio says to Romeo's father "My noble uncle, do you know the cause?" (somewhere around line 150) and later in the scene he greets Romeo "Good morrow, cousin." (about 15 lines later).
No, Benvolio (Romeo's cousin) is the peace keeper of the play. Tybalt is the complete opposite. He fuels the fight in Act 1 Scene 1, "Turn thee Benvolio, look upon thy death." In Act 3 Scene 5, Montague (Tybalt's uncle) calls him a "Princox", which is basically saying that he is more trouble than he is worth.Tybalt is a fiery character, and is, in no means, a peacekeeper.
In Act 3, Scene 1 of Shakespeare's "Romeo and Juliet," Tybalt expresses his willingness to fight when he says: "What, art thou drawn among these heartless hinds? Turn thee, Benvolio, look upon thy death." Here, Tybalt eagerly taunts Benvolio and shows he has no hesitation in engaging in a fight.
Benvolio, at the Prince's request, explains the two fatal swordfights.He tells the Prince that Romeo tried to talk Tybalt out of fighting and tried to make peace with Tybalt, and that Romeo reminded Tybalt that the Prince had forbidden fighting. He relates how Tybalt and Mercutio insisted on fighting, and how Romeo had knocked their swords away from each other with his arm and had rushed between them trying to stop the fight.He explains that Tybalt started the fight.
The fight in Act 1, Scene 1 of Romeo and Juliet was started by servants of the Montague and Capulet households, who were fighting with each other. The specific servants involved were Benvolio, who was a nephew of Montague, and Tybalt, who was a nephew of Capulet.
Mercutio and Benvolio trade insults with Tybalt. Romeo arrives, but refuses to quarrel with Tybalt (who is now his cousin by his secret marriage to Juliet). Mercutio is willing to fight, but is killed by Tybalt as Romeo tries to intervene. Romeo, enraged, pursues and kills Tybalt. Prince Escalus banishes Romeo.
