Why are they changing Rosalie in the middle of the Twilight series?

Answer 1

Carlisle avenged Rosalie because he found her on the street, almost dead. Carlisle can't stand seeing people in pain and agony that he avenged her after she was raped by her very own fiance`. Though Rosalie doesn't like being a vampire, if she really had the choice, she would of said no. She would trade anything in the world to be human again, she would even trade her beauty. That is why Rosalie doesn't want Bella to become a Vampire. HOPE THIS HELPS!!
