40. Kilgrave, 'Jessica Jones'
"Jessicaaaaa!" If you've ever been filled with dread simply by hearing your own name called by someone who "loves" you, the telepathic predator no doubt struck a nerve. Actor David Tennant is best known for playing one of TV's most iconic heroes on Doctor Who, and his turn as a villain sees him feed more than a little scenery into his maw. But the Kilgrave concept is so chilling, and so resonant with all-too-real abuse, that the character still belongs in any discussion of TV evil.
