Rosalie doesn't think Bella should want to be a vampire. She was forced into this state against her will, and she would rather be dead than be a vampire. Bella is still young, and Rosalie thinks it's stupid to want to throw her life away like that. There is much of her human life that Rosalie would kill to have, but Bella doesn't care about any of it.
starve
every way he could think of.
not eating and starving himself
He hasn't tried NOT to kill himself. He has tried to kill himself many times but decided to live as a 'vegetarian' vampire feeding on the blood off animals in stead of being a monster.
He didn't die at all. his father was a minister and he was part of a mob chasing a vampire when the vampire bit him but before it could kill him the mob chased away the vampire and carlisle crawled into an alley where he turned into a vampire.
You can't kill a vampire - it is already dead.
WE can kill a vampire using a silwer sword
He jumped from great heights and tried to starve himself.
