Or perhaps chain him up by the arms, and lower him very slowly, feet first into boiling water. Or start chopping bodyparts off until there is nothing left, or maybe having him savaged to death by a pack of rottweilers/pit bulls.
Arsewipe is in dire need of a good slow boiling. Or stick his head into a microwave oven, and cook it until the water in his brain boils and his head bursts like a melon hit with a hollowpoint round. Alternatively hit him with a cricket bat, starting at the feet, arms, fingers, toes, knees, until he is generally battered to death.
I can think of plenty of nasty things to do to him with a blowtorch, or slowly burn him to death, pinpoint target by pinpoint target using a soldering iron, until he dies from third degree burns.
Fucking woman abusing cum-stain on the festering rectum of sub-humanity. He is a disgrace to spesh people everywhere, and is unfit to be autistic. A waste of an autie/aspie brain, that could have been given to a decent human being. Fucking cocksucking shouldbe-NT oxygen thieving rat bastard that he is.
Pressing him to death with the old fashioned peine forte et dure used to execute 'witches' back in the burning days would be good, as would crucifixion with rusty nails. Or cutting him a thousand times over, rubbing human and/or dog shit into the wounds and leaving him to die of infection.
I sincerely hope he dies a miserable, agonizing death of fournier gangrene.
