I have unwittingly discovered a new torture device. Take whatever group you wish to torture and put them to work on a project. Give them a very definite deadline. Force them to work long hours, with constant promises of reward and potential future opportunities. When the deadline arrives, keep everyone awake and ready in case of any problems, for three days. Finally, instead of granting any sort of break or relief, put them back to work demanding more of their time, energy, and will to live. After a week of that, they will be willing to do anything.
While anything can be potentially bad for you, the Evil Overlord, for an individual skilled in torture, this can be a great asset. You will quickly recognize the breaking point, and be able to direct the pending explosion skillfully to achieve many of your goals. Goals that include removing the competition, getting media attention, or even just practice. The point is, you have now learned about a very effective torture tool. Any victim who happens to survive this torture method, will be able to wear the mantra, “I’m not dead yet.”
