Why can't you freaking die, you devil!!!

"Get on your knees, right now and put your hands behind your head!!!", John yelled at William as he whips out his Glock 19 Gen 4 9mm Pistol and points the mussel at William's forehead. William smirks at John and says, "Oh, my good lad, shoot me if you please but, you should know, that I can't die." Then, his face lights up. "Oh! I know a BETTER way to slither on out of here without a fuss!" His legs turn into purple smoke and he floats on over to where the lady is. The lady screams as William grips her up off the floor by her long brown hair. He puts his hand next to her head and in his hand, the same gun John has mineralized into his hand. You hear the BE DOO, BE DOO of several cop cars screaming around the corner. You guessed the lady at the desk called the police when it all when down. You run past John to the double glass doors. You see red and blue lights and you see a TON of police officers running toward the doors with bulletproof suits on and AK-47's. Big ones, too. You whip around to a horrific scream and long sickening snap. You see the lady falls to the floor, dead. "Sorry. They took to long to save her . . . ", William says, not sorry at all. You glare at him and yell, "You murderer!!!! You are a psychopathic murderer!!!!" You run to John and grab his Glock out hands. "Hey! I was using that!", John says as you walk away. "No, you weren't. You were standing around.", you shot back, frustrated. Then you hear the sound of shattering glass to your right. You turn to see the cops smashing the glass to get in because William locked the doors. Somehow . . . there are no locks on the doors, which make no sense. It's a police station. Then . . . why can't they get in? You whip back to the demon hovering in the air. You aim the Glock at his forehead and fire 6 rounds. BLAM! BLAM! BLAM! BLAM! BLAM! BLAM! You expected them to go through his forehead and out the back of his skull with a splatter of blood on the ground. But, that's not the case. The bullets' shot right his thought his head with whips of purple smoke and ricochet of the granite wall. You turn to see if the police finally got in. Before you can say, "Wow", they slam into the glass with hand-held steel, battering ram. The glass rains down onto the floor as they crush it underneath their boots as they sprint into the station. They create a circle around the flouting demon, all 16 Remington 870 Express Tactical Magpul shotguns aimed at him. "GET ON THE GROUND, NOW!!!!", yells the ripped dude, who you suppose is the leader of the group, with a close cut haircut, army style. "OR WE'RE GOING TO OPEN FIRE!!!!" Tense silence flows around the room. William scoffs and says, "Um, excuse me?! I have a name! You can call me William! Or Vincent. Or "The Purple Guy". I have a lot of names. But don't call me the demon! Didn't your mommy teach you any manners? Well, I guess I'm going to have to teach you some!!!" William shots toward the guy, mouth wide with its razor-sharp teeth and his large red eyes. The leader starts firing at William rapidly. William slams into the guy and pins him to the ground. You scream in horror as William opens his mouth wide like a hippo and clamps it on the guy's head. The guy screams and drops dead. William unhooks his teeth from the guy's head and licks his now bloody teeth with his long pink tongue, the only thing that's not purple on him, aside from his eyes and teeth. He floats up and looks down at the rest of the crew. Then, he looks at you. "That one person who always ruins my fun . . . ", He says, scowling at you. He lets out a horrific laugh, flies down, and smashes out the door . . . . .
