Yeah, I wouldn't worry about her calling you a "bad person." Children and teens (and even adults) often get angry and lash out when forced to do something they don't like, but hopefully she'll understand in the future. Tell her it would make you a bad person if you didn't try to help her have a wonderful life in the future, and that's what you're trying to do. She doesn't have to agree. A big part of being a parent is making decisions for your kids that they don't like.
