If werewolves and vampires are considered forces of evil, what are considered the forces of good?
The forces of evil you have described above can also be forces of good. In different books and movies, all of these creatures are percieved differently. In Stephani Meyer’s Twilight series, there are good and bad vampires, and the werewolves aren’t evil. Demons are pretty dark forces…I don’t think I’ve ever heard of a good demon. Ghosts, actually, are spirits who have lost their way. Some stay behind to guide their loved ones, others just want to have some unfinished business completed. Ghosts aren’t evil, they just need help. Thay can serve as our guardians, and therefore be considered forces of good. Faeries can also be good nature spirits who watch over the forests, as are other mythical creatures.
