I believe evil exists separately from us. Have you ever wondered what might happen if your conscience—through no fault of your own—was captured by a demon? If, directed by an evil force, the anger and hate inside you was no longer restrained but instead loosed on others? If—without that inner voice restraining you—you could do anything you wanted to? Given our flawed, sinful nature, I think the potential for this happening exists in all of us. So we must fight all manifestations of the Devil’s work. And support harsh punishment of criminals as a deterrent. 
(Note: critics call this
“the myth of    pure evil.”)

I can be powerful. I can often get what I want by intimidating and instilling fear, by verbally and/or physically threatening. Since this only succeeds if the threat is believable, I've got a reputation associated with verbal abuse and resorting to actual physical violence— even condoning torture! (Note: some who lack restraint use the old threat system, based on “Give it to me or I’ll hurt you” or “Pay me and I’ll quit bothering you.”
A more modern approach is to file / threaten a lawsuit. Of course sometimes abandoning restraint—even going to war—
can be justifiable.)
