That's pussy. We can get all the physical torture we want, but in the end, psychological torture is where you at, and the end point is to keep them alive for as much time as possible and torture them endlessly in that time.
For instance, you put them in a coffin surrounded by water and constantly play Metallica at eardrum breaking volume, force feeding them, and letting them live in their shit and piss. For the rest of their life. If they get sick, pull them out and give them medical care, and put them right back in.
