30. Officer Dawn Lerner
So far, the series has featured two major long-running bad guys: The Governor and Negan. And over the years, the survivors have matched wits with a handful of petty tyrants, like the Terminus cannibal Gareth. But Dawn Lerner was one of the show's more sympathetic mini-villains: the protector of Grady Memorial Hospital, a ruthlessly pragmatic cop and someone who saved useful humans so they could be employed as slave labor. (She kept them locked up, yes, but to be fair, she claimed it was for their own good.) As played by Christine Woods, Officer Dawn was not outright evil – she was just ice-cold by necessity. If she hadn't reflexively shot poor Beth in the head, she might still be the Queen of Atlanta today.
