It's the not too distant future and everyone has eye implants which allow video recording. Kidnap a young woman and take her to a soundproof room. Bind her to a scaffold in front of a mirror and make her watch as she's slowly disemboweled alive. Listen to her screaming and begging and crying as she watches he belly worked over carefully with a blade. Record it all from her point of view so that her perspective of watching her intestines pulled out can be watched over and over again, staring down over her breasts at the mess of tubes and coils left hanging between her soft thighs. Sew her back up carefully and heal her wounds (using future medical tech) after some time, and then make her re-watch the video day after day. Finally, after a few weeks of this, do it again, but this time cut her bowels out completely and dump them between her feet and leave her in front of a mirror to bleed out while she screams and cries. Of course if this future had perfect VR / neuro-simulation that would be the way to go since I have no desire to actually hurt anyone in real life.
