What if the TORTURE occurs during a random time in the next 3^^^3 seconds, not right at the beginning? Also, I think we definitely require a limit on sanity damage because otherwise the scenario is being tortured for 50 years and then spending the next 3^^^3 seconds being insane which Vastly outweighs the ordinary scenario of being tortured for 50 years.
In the original scenario, where just some random person got tortured, no constraints were specified about eir sanity or lifespan post-torture.
