Are there any Gryffindor Death Eaters? The answer is yes, but only one. Peter Pettigrew, better known as Wormtail, is the only known Death Eater to have been sorted into Gryffindor House while attending Hogwarts School of Witchcraft and Wizardry.
Pettigrew was a close friend of James Potter, Sirius Black, and Remus Lupin, and was a member of the Marauders. He was sorted into Gryffindor upon his arrival at Hogwarts, and became a loyal friend to the trio. He was a timid and nervous boy, and was often bullied by Sirius and James.
Despite his close friendship with the Marauders, Pettigrew was a Death Eater. He was a loyal follower of Lord Voldemort, and was instrumental in helping him return to power. He betrayed the Potters to Voldemort, and was responsible for the death of James and Lily Potter. He was also responsible for the capture of Sirius Black, and for the framing of Sirius for the Potters’ deaths.
Pettigrew was eventually revealed to be a Death Eater, and was sentenced to life in Azkaban. He was eventually released, and rejoined Voldemort’s forces. He was killed by Voldemort in the Battle of Hogwarts, after Voldemort realized that Pettigrew had betrayed him.
Pettigrew is the only known Death Eater to have been sorted into Gryffindor. While it is possible that there are other Gryffindor Death Eaters, none have been identified. It is possible that some of the other Death Eaters were former Gryffindors, but it is impossible to know for sure.
Overall, Pettigrew is the only known Gryffindor Death Eater. He was a loyal follower of Voldemort, and was responsible for the deaths of James and Lily Potter. He was eventually killed by Voldemort, and his death marked the end of the Death Eater’s reign of terror.
