I would take him to an abandoned warehouse, hang him up on a meat hook by his tied hands, and beat him half to death with
large blunt objects, I would then cut him down at his weakest point, sit him upright and force acid down his throat.
I would then cut off his hands and feet, pull out his teeth, drench him in Gasoline and burn him to no more than a crispy mess.
I would then dispose of his remains by putting it in a barrel, and throwing it into the sea.
