A mass murderer has been executed.
However, an all-powerful god takes their consciousness and re-inserts it into a new special body. They are forced to exist in all of perpetuity.
The god then opens a torture museum in a supernatural realm. You can pay 100 dollars for 5 minutes inside the realm. Once inside, you can see the mass murderer trapped inside a box. You are invited to pull a lever which will administer various degrees of electrical shocks, thus torturing the killer. If you apply a high enough voltage, you can kill them.
While you do so, you can hear the killer scream and/or plead.
The murderer is resurrected if they ever get killed. Any mental and physical damage they get from the shock also recuperates at a supernatural rate.
Please assume that there is no feasible way to oppose the will of this all-powerful god or to interrupt/destroy the torture museum.
The all-powerful god has announced that this torture museum will open tomorrow and he has explained how you can give your 100 dollars to him if you want a turn.
Please assume that the all-powerful god will take infallible and effective steps to protect you from the legal and social ramifications of using the torture museum.
Please assume that the mass murderer is well-known and tons and tons of people have expressed their outrage at their crimes.

Now OF COURSE no one on NSG would pay 100 dollars to do this, because everyone here is nice (...right?).
The same can't be said about the world as a whole though.
What I want to discuss instead is this:
Keeping in mind all of the assumptions of the hypothetical, and based on what you know/assume about human nature... what percentage of the world's teenage to adult population do you think would try the museum AT LEAST ONCE... 10 percent? 25? 50? 75? 100?
