Poor people are already "required" (i.e. paid enough money to do it willingly) to risk their lives helping rich people get up and down the mountain. This doesn't seem substantially different.
Hauling a heavy dead body down the mountain is a lot tougher and more dangerous than carrying some extra oxygen bottles and food. In the death zone the porters are already working at the outer limit of human performance.
This. Never actually been in the death zone - my highest has been just under 7km, but it was hard enough carrying my own stuff up and down.
That's a neat trick, quoting a word that would have made the parent comment unreasonable, as if the parent comment had actually used that word...
