Harry Potter represents the devil. I think Voldemort is supposed to be God. The "bad guys" like Bellatrix LeStrange and Draco Malfoy are part of a group called the Death Eaters who are also known as an Inquistorial Squad -- i.e. they are the Catholics. They are awaiting the return of Voldemort and the destruction of Harry Potter and they are hoping for great honors because so few of them stayed loyal to Voldemort when he was invisible... Get it? It's all a dark, twisted mirror of what is really happening during the Apostasy with Harry Potter trying to finish the job and take out God entirely. Only a few infiltrator-types are left to keep His memory alive.
Check out the name "Draco Malfoy." "Draco" refers to the dragon or snake, like Satan, and the last name is a medievalistic play on the French "mauvais foi" or bad faith. That is because to a witch like JK Rowling, a Catholic is the one who is the betrayer and the monster. Therefore she gives him the name that an evil character would have. Although the names of the good characters are not much better, like "Ron Weasely."
L'Osservatore Romano, the ludicrous mouthpiece of the fake Vatican ( which praises deep occultic rock music as well ) was actually correct to say that Harry Potter was about the battle between good vs. evil, it's just that, as the devil has almost succeeded in doing in the world at large, everything is reversed. The audience is invited to cheer for the villains.
