Hermione is a great role model for girls. She is smart, beautiful and strong. Ginny is a great role model for girls. She doesn't (most times) let her crush on Harry stand in her way to be a great fighter. Luna is a great role model for girls. She is weird, but doesn't stop being herself because her peers tease her.

Bella is not a great role model for girls. She jumps off a cliff when her boyfriend broke up with her.
