Snape’s duplicity had audiences constantly trying to figure out where his true loyalties lay.

He was deeply in love with Harry’s mother, and vowed to protect him for her sake.

Yes, Snape was bitter and mean, but unrequited love can do that to a person.

But, the fact he willinglyshared his body with Lord Voldemortmakes him at least worthy of an honorable mention.

After that litany of misdeeds, his sticky end seems a little more justified.

But Corban Yaxley, played byPeter Mullan,is a truly terrible tyrant.

When the magical Polyjuice potion eventually wears off, it’s the true Barty the audience sees.

In his final scene, he shows off hisDeath Eater dark mark like a badge of honor.

Like his companions, Greyback poses the worst kind of threat to those considered lesser wizards.

He relishes his role as a Snatcher tasked withhunting and capturing muggle-borns and blood traitors.

It’s enough to turn the stomach of even the most devout Death Eaters.

Many people cheeredwhen this wicked witch finally met her match.
