This is exactly like that Star Trek episode about a planet where people threw a big ceremony when their life’s work was done, basked in the recognition, then voluntarily and happily underwent liquidation.
Unfortunately I can’t remember which Star Trek it was.
James T. Kirk would never have allowed this to continue; he would have yet again violated the Prime Directive.
Captain Picard would have struggled against his natural revulsion for the system but have beamed the gent back down to undergo it.
If it had been Deep Space 9, they probably woulda had a suicide pod on board the station.
(P.S.:When I think of that episode I wonder: was EVERYBODY on that planet some kinda genius? Was this kinda death just for the elite, like the Pyramids?)
