Why can’t it be? I know Carlisle’s pacifist and all that, but you guys should really consider becoming a superhero squad that takes down the bad vampires and protects humans.
This really does subvert the whole damsel in distress trope. Bella won't let Edward put himself in danger to protect her. As much as he wants to protect her, she wants to protect him. And of course, in Breaking Dawn she really gets to.
