It’s true Bill really did love the bride, but perhaps in the only way one killer can to another killer. As he says rite before he shoots her “This is me at my most masochistic”- he’s hurting/torturing himself by shooting her, but hey if ya gonna run off with the guys unborn child, letting him think your dead, knowing fully well he likes to kill people, you have got to expect some retaliation.
However i disagree that she is the villain in this bloody tale, she is a mother protecting not her own interests but those of her child. When he shoots her i dont think shes as bothered about it as she is the fact she assumes the baby inside of her is dead. As we see when she wakes up in the hospital, clasps her womb and bursts into tears. Ultimately Bill is psychotic and deserved to die, and she deserved to be reunited with her child, so everyone is happy. ;D
