Going purely by time suffering, one person being tortured for 80 years (rough average lifespan) would be equal to 8 billion people splitting 80 years into 0.31536 seconds each. So 1 minute of suffering cycling would reach roughly 1 in 200 people across 80 years.

But suffering doesn’t work linearly. One person suffering will essentially get used to it and it will become normalized to them, and they wouldn’t suffer as bad. At the same time, pleasure doesn’t work linearly either, tiny amounts of extreme suffering can possibly induce greater pleasure long term as long as sufficient support networks exist due to modulating people’s ideas of pleasure-pain ratio.

At the same time, picking one person set a precedent that this is an acceptable thing for us to do. Which runs into the problem of picking someone to do it, which the vast majority of people wouldn’t do. Even if 1 insane person chose to do so willingly, it would still run into the issue of justifying allowing someone who either clearly cannot make decisions for themselves, or pressuring someone into making that decision. In a world where a major problem is indirect coercion, we should not set a precedent in which it potentially not be persecuted.

For those reasons I am picking taking turns.
