3. Lori ("The Walking Dead")



How many times does Carl have to almost die before Lori checks to make sure that her son is where he's supposed to be? And then there's her pattern of reckless behavior, like taking a bunch of morning-after pills in order to induce a miscarriage and maybe kill herself in the process. Or taking off in a car after dark to check on her husband, and then crashing it… leaving her son in danger of losing both parents in a world filled with zombies. Plus, she raised a kid who is such a little brat that he stupidly taunts zombies and wastes valuable weapons.
