Encountering Evil - S1.E24

Is the presence of evil, real? While many believe that there is some darkness in our world, is it a malevolent being like the Devil? Or does it emanate from strange locations like the Cecil Hotel, where murders and suicides have occurred for nearly 100 years? Perhaps evil is something that tempts humanity, or a feeling that invades us when we are fearful or confused. Is it possible that humans themselves, draw dark entities and ghoulish presences out of hiding?
