Well, you’re not including in your assessment the exsanguination of all those cattle - but, on the other hand, we’ve never actually seen them/anybody do that.
I’m sorta in favor of fairies, leprechauns, elementals - and the projected products of the human psyche - for the CEIII classification. Most of those can be amoral and mischievous, but I don’t think they’re demonic...
My guess is the cattle mutilations are deep state operatives. Sounds like something up their alley. Scare the hayseeds. Etc. My guess is you cannot just land on a planet and goose a cow. First off, you have no defense from the lower forms of life. See War of the Worlds. Lol.
