The dark side of nature is not a bad thing. We cannot live without it. Many attempt to deny it within themselves. But it isn't healthy. Even darker entities can have honor and love. The stereotype is just that, a stereotype. If you look at many deities, they have a mean streak in them all. Some lean more toward the dark side (Hekate) and others more toward the light (Aphrodite).
There are malicious and benevolent spirits of every form, light and dark. Their nature is only how they act, not why they act.
Some people like high tech security alarms on their houses, others like big dogs named Killer and a loaded shotgun.
