1 billion dollars if you subject 10,000 people to horrors beyond our comprehension
You do not go to hell for this, nor are you punished by any governing body. You will be transferred 1 billion USD to your bank account tax-free if you take this offer. This money does not have any major inflationary effects on the economy, given you use it wisely.
The people will be subject to these horrors for 100 hours. They do not know your name or anything about you. But they will remember. You do not know anything about them either. The people are chosen across the globe at random. You cannot attempt to find these people and make amends with them. If you try to do so, you are subject to these horrors for 100 hours and the money is taken away.
Do you take this deal?
