Kitty (Becca Tobin), Glee
Even Glee's biggest villains have been able to occasionally pull back the curtain on why they’re so hostile. Unfortunately, the softer side of McKinley High’s newest bully, Kitty, is nowhere to be seen. She's racist, judges people's weight and seems generally intent on controlling (and ruining) the lives of others without an ounce of reason or compassion. Hopefully, the writers will start unpeeling Kitty's layers soon.
