Viper

This world is not fair, and Viper knows that since before. She understand that to get what she wants,she either needs to fight for it, or take it away from someone else. It's never enough to just work hard, it's never enough to be kind and sincere, because at the end of the day, people would chose the one they can benefit with. And that's what's precisely what she's doing. Making other people fall in love, and showing them how miserable they will be without her.
