If you grew up with a more fundamentalist perspective, you'll understand what I'm about to say here: for some folks, "everything is the Devil."
More accurately framed, for some folks, everything they fear, distrust, or don't understand is attributed incorrectly to Satan.
Around 2007, I had an experience that framed things differently for me: what if instead of trying to avoid Satan, we tried to find Christ?
"Christ is reflected in the sky. Christ is reflected in the changing of the seasons. Christ is reflected in the moon. Christ is reflected in trees. The flowers. The sounds of nature."
And so on.
At the time, I remarked something to my mother along the lines of, "Some people are so dedicated to avoiding Satan that they end up running into him around every corner."
Most all of us have misgivings, fears, doubts, uncertainties, and so on. We don't, however, have to create more for ourselves, and we don't have to prevent ourselves from my growing as people by suggesting that all the things with which we're unfamiliar are actually controlled by the forces of evil.
Speaking strictly in personal capacity, I don't necessarily hold to the belief of a specific Satan- perhaps there are negative, even malicious, spirits that exist, but I'm not sold on the idea that there's one king of the devils, nor have I encountered such beings.
I have, however, experienced directly the help of beneficent beings and Christ and the Blessed Virgin Mary.
That being said, there are people who claim to have had terrifying (and traumatizing) encounters with evil spirits, and I'm not going to be so arrogant as to claim they're mistaken in their experience.
Let us look for and to Christ in all things.
