I would bury them head deep in a sea of the smelliest, bloodiest, most disgusting, burning SHIT imaginable. This will be their only caloric intake, gallons shoving into their mouth with each breath. Shit monsters swim around them to punch them in the face, rape then, rip their skin apart. Only their eyes emerge from a world of SHIT. They can only see two things - their friends and families burning in infinite agony, and US, high in the skuly, unmolested, fucking THEIR women. Their minds reset every few seconds so it is impossible for them to ever get accustomed to 1/1000000th of the pain we suffer from on a daily basis.
