Demons Released

Do you ever think about how so many stories talk about how they need to keep the evil things in hell, they can't let the darkness out, and if they do something awful will happen?
What if the evil was already out there? There's a saying, "Monsters don't sleep under your bed, they sleep inside your head". Think about all the darkness that's already in the world: disease, murder, suicide, pain, heartache, suffering. All these horrible things already exist, so I say bring it on!
