What are some opinions and attitudes Mercutio has about and towards others?
Mercutio does not like to see his friends moping and sad; he is much too merry a character for that! When Romeo is pouting about Rosaline, both Mercutio and Benvolio try to get him to forget about her and check out the new girls at the Capulet party. Mercutio thinks that people should be as merry as he is, and if not, then he will try to cheer them up (like talking Romeo out of paying too much attention to his bad dream with his Queen Mab speech). In the beginning of Act III, Mercutio shows that he projects his own personality traits onto others when he speaks to Benvolio. Mercutio taunts Benvolio about being ready and willing to fight at the drop of a hat, but it's really Mercutio that fits the description, not the mild-mannered Benvolio. He wishes that others would be more like him, which is why he projects his own traits on others. His opinion of Tybalt is that the young Capulet needs to be taken down a few notches and have some of his nine lives (referring to Tybalt as the Prince of Cats) removed. Of course, Mercutio is just the one for the job, in his opinion. As for the Montague/Capulet feud, Mercutio is neutral; he'll fight anyone just for the sake of fighting. While Mercutio hangs out with Montagues, he was on the invitation list to the Capulet party. This shows that he has no specific loyalty to one family or the other in the feud that rocked Verona.
