Evil exists.  That much is incontrovertible.  But are the characters I have created truly evil, or merely outcasts, mutants, and grossly misunderstood creatures?  I call them only Ghost, Vampire, Witch, and Demoness, because these are queens of their kind, and dropping their personal names is a sign of respect in this dark culture that I am postulating.  They cannot have reached such important positions without as a bare minimum the ability to be totally bad-@$$ when needed.  So they are not completely nice girls, and the same goes for their companions and associates.  Ghosts can be vengeful, Vampires drink blood, Witches practice magic that may not be of the light, and Demons, well, they are certainly not "like us" to say the least.  But among the "Things that go Bump in the Night" evil is as evil does.  I leave it to you to decide how far that goes...
