(A/N: I don't know where this idea came from, but I just thought of it while I was watching Eclipse, so here it is. Enjoy!)
Wrong Choice
Rosalie stalks her prey silently, gracefully, elegantly.
She finds Bella's pale neck and clenches her hand around it, hearing the human struggle against it but having no success.
Before Rosalie can stop herself, remind her that this is wrong, she is ripping the other girl into pieces and chunks—a forearm here, a thigh there. The blood streams everywhere, but she doesn't let it bother her one bit. She needs to finish this without distraction.
Rosalie knows Edward will kill her for this, but she doesn't care. It had to be done. Bella would have made the wrong choice otherwise.
It's better Bella die than become a cold, lifeless vampire.
