Show me an animal that kills for fun and/or an ego boost and/or greed and I will believe it's evil, until then, humans own that real estate.
A couple of weeks ago, I came home in the early evening and there was a cicada chilling on my porch. A few hours later, I go out there to wait for my girl to come get me and it is dead, gutted and jammed between planks. And oh yea, covered in black ants. It was creepy as f*ck, but I could not look away. From what I could tell, the ants were trying to pry it free. There were a couple that must have been look outs or something because they would break away from the group now and then and scurry around the perimetre in circles and then rejoin the effort.
When I came home a few hours later, nothing, not a sign of any of them.
Not evil, but chilling nonetheless.
