Tybalt is asking here why his men have drawn their swords for the Montagues, as they are not worth their time. He sees himself as superior to the other, and is arrogant.
"look upon thy death" "turn and draw"
Tybalt is violent, and all about protecting his family name and reputation. Here we see him trying to protect his reputation of masculinity, so he tries to intimidate the Montagues and get them to fight him.
"now seeming sweet, convert to bitterestgall."
He is foreshadowing events later in the play, that things will go wrong. It is also the first big indication that Tybalt is going to really stirthings up with Romeo.
"by the stock and honour of my kin, to strike him dead I hold it not a sin."
Tybalt will do anything to protect his side of the feud, even if it means killing someone. This quote tells us that he is dedicated to the Capulets and doesn't think it is a sin for him to kill somebody to protectthem.
"What, drawn and talk of peace? I hate the word/ As I hatehell, all Montages and thee"
Tybalt's language is full of hatred, this quote suggests that he is one of the main catalysts in continuing the feud between the families. He compares the idea of "peace" and "hell" suggesting that Tybalt representsugliness that lies below the surface of Veronesesociety.
