The only Death Eater who was sorted into Gryffindor was Peter Pettigrew.
Despite his later allegiance to Lord Voldemort, Peter was originally sorted into Gryffindor. This demonstrates that even the bravest and most noble house can sometimes produce individuals who make terrible choices.
Peter's betrayal of his friends and his subsequent alignment with Voldemort highlight the complexities of good and evil, and how even those with seemingly good intentions can be corrupted by darkness.
His actions ultimately led to the deaths of many, including his best friend, James Potter, and James's wife, Lily.
While Peter's sorting into Gryffindor might seem contradictory to his later actions, it serves as a reminder that even the most noble houses can produce individuals who choose to walk down a dark path.
