If you've ever seen a "slasher" film, this scenario is going to be familiar to you:
The mad, "pure evil" slasher comes after his victim with an axe. There's a loud "thump!" and a scream. The victim looks in horror at his shoulder, now issuing copious spurts of fake red blood.

There's no doubt. The mad monster is evil. Pure evil. There's no way he or his actions could be described other than calling him evil.
