Mona Vanderwaal (Janel Parrish), Pretty Little Liars
What Makes Mona a Sociopath: Mona is the original “A.” She tortured her best friend for over a year while playing the sweet, caring, loyal friend in public. She made people laugh, even if she later made them bleed.
Why We Still Love Her: After learning that Mona may actually be a pawn for the “A” team, we worry that she was just overly vulnerable to a group of villains far more evil than she.
