He decided to shoot the mocking fucker.
He took a few steps forward, leveled the gun and the shocked man's face and with a blast from the gun, Ben turned his tormentor's head into red a pulp of brain, bone and blood. His headless body fell to the floor, never to laugh or smirk again.
"Fuck you, you bastard!" Ben screamed "and go to Fucking Hell!"
Ben sincerely hoped the fucker would go to Hell to be raped by demons for eternity. To be injected with various serums over and over and over again to change him into whatever pleased they're demonic lusts and perverse tastes.
Ben knew there was one thing left to do. He put the end of the shotgun in his elongated mouth and just managed to pull the trigger.
The back of the half donkey's head exploded in red and Ben died instantly... but he died as a man... not as a used up beast.
