5. Dr. William And Dr. Dakota Block - Planet Terror (2007)
At first I was just going to put Dr. William Black, until I realized Dr. Dakota wasn't exactly mother of the year. When they're first introduced in the movie, you can tell they don't have warm and fuzzy feelings toward each other. There's also the fact Dakota appears to be planning to leave him, and take their son with her. A few zombie and gore-filled minutes later, we find her secret lover is dead, and William puts two and two together. I can understand being in a blind rage when you find out your spouse has been having an affair. I just don't think I would get mad enough to murder them in a hospital filled with witnesses. But still, she manages to get away and pick up her son. To her credit, she has a gun. She loses points when she leaves him in the car alone with the aforementioned loaded weapon and tells him not to aim the gun as his own head. Unsurprisingly, the gun goes off and he dies. I know the argument could be made that she couldn't use her hands, but why didn't she just have him follow her, and told him to shoot if a zombie popped up? Aside from being bad at the whole parenting thing, these are probably the last people you want to be stuck with when the zombie apocalypse first breaks out.
