Throughout the Harry Potter series, the gentle half-giant Rubeus Hagrid is known as many things. He's a father-like protector of Harry, the Hogwarts groundskeeper, the Keeper of the Keys, a Care of Magical Creatures teacher, and, to those who believe in the Hagrid Death Eater theory, an avid follower of Lord Voldemort. Although Hagrid is one of the most memorable and adored Harry Potter characters, Reddit user /u/Whoofph dives deep into the pages of the original seven Harry Potter books to determine whether the beloved Hagrid is a Death Eater or not. According to their research, all signs point to yes.
Hagrid might act suspiciously at times, with his bumbling mannerisms and strange living habits - but is Hagrid a Death Eater? /u/Whoofph's theory is that Hagrid is actually putting up a large facade, spending the entire saga acting as a conspiring agent of the dark arts, benefiting the success of He-Who-Must-Not-Be-Named until the bitter end. Remember, Hagrid fans, it's just a theory, and only one theory.
