Harry Potter: Ranking Every Death Eater From Worst To Best

There is no denying Peter Pettigrew is a despicable character, and possibly one of the most hated in all of the Harry Potter franchise. After growing up with James, Remus, and Sirius as one of the Marauders, Wormtail went rogue and defected to Lord Voldemort and the dark side of magic.

Though he is something of a pathetic creature, and suits the rat that he hid as for so many years, Peter Pettigrew proved himself to be incredibly useful to the Dark Lord.

He revealed to He-Who-Must-Not-Be-Named the secret of where the Potters were hiding, allowing Voldemort to kill Lily and James, and in theory at least, Harry. Though he went into hiding after the first Wizarding War, he sought Lord Voldemort in the Albanian forest, and was instrumental in the revival of the Dark Lord's physical form.

In the books Voldemort punishes Pettigrew for hesitating to kill Harry by taking his life, however in the movies, the man known as Wormtail does not actively let the Dark Lord down. Though he is tricked into the release of Harry and co. from their captivity in Malfoy Manor, he stayed loyal to Voldemort to the very end.
