You must take this deal; trade money for torture, but do you forget the pain to reduce your earnings?
This is a deal you can't say no to. A supernatural being has forced you into it, but at least they're offering a prize for your pain.
You will be subject to one from of torture. You are allowed to choose the method, but it must be a real form of torture used at some point in human history. You arent allowed to cheat and choose something that would end very quickly/with little pain (for example the guillotine wouldn't count, something that wouldnt be a significant mental/physical challenge for just 1 day wouldnt count)
The being will teleport you back in time to when it was happening, or to the place if its a modern form, and you will be accused of a crime bad enough to be punished with that torture. You will experience the torture until you die, or if its not something that kills you, for 1 full day.
The prize for going through this is enough money to last your whole life. You will never have to worry about bills or expenses of any kind again and will magically have enough money to buy anything you need. You cant use this ability to buy a mansion or live a very extravagant life, but you will be able to support any upper-middle class lifestyle for free, and can choose to work for more money if you want to try and get rich.
But, the being also offers you an alternative. You can give up the infinite money prize, and instead take $1.5 million. One time payout of tax free money that doesnt replenish, so you'll probably have to work again.
In exchange, after the torture is done, you will have no memory of it whatsoever. It will be as if it never happened then you'll just wake up one day knowing logically you did the deal, and with $1.5 million.
Either way, you will come back physically unharmed, but if you choose unlimited money all mental trauma stays.
Are you forgetting it?
