It is, indeed, the fucking Devil, and the Devil is going to town on these not-demons that are just all over the place. It's actually pretty cathartic, being able to crush something's skull between his hands and just have the skull-crushees just never run out. He smites these abominable creatures, strikes them down like the terrible weapon of Heaven that he is. This had been his purpose once, destroying what their Father would find hateful in His sight.

His bloodbath is interrupted by the approach of something large and horrible. Another thing that his Father would find hateful, no doubt, but he is trapped still in this vessel. It would be something of a challenge to take down this giant beast while stuck a mere fraction of his true glory.

And Johnny isn't even a blip on his metaphorical radar. Sorry, kid.
