Ezra Is “A” on Pretty Little Liars?! 7 Other Secretly Evil Characters

The Season 4 summer finale rocked the Pretty Little Liars fandom with the revelation that Ezra could be "A". This handsome teacher has been Aria's love interest since day one — could he really be evil?

We'll have to wait for a while to get the full story on Ezra, but we believe that he could end up being as guilty as he looks. Why? Because he'd be far from the first seemingly-good TV character to turn out to be secretly devious. Making the good guys go bad is a time-honored tradition; the good news is, shocking twists like this can work out very well in the long run.

In light of the Ezra revelation, here are seven examples of good characters turned bad that really worked. Hopefully, if Pretty Little Liars does go down this path, the results will be as good as these shows.
