I'm glad you took it upon yourself to create a post ranking system. Much sophisticated.
The vast majority of people who have died on Everest didn't go it alone. They climbed with friends, partners, people they loved, etc. Or they paid a shit ton of money to an expedition/guide to get them to the top. Either way, there is a huge investment from the climbers, the guides, the Sherpa community, the government of Nepal, etc. Now, don't you think that if they could bring these people down off of the mountain, they would?
I linked an article below for some context that will give you an idea of how hard it is to rescue people via helicopter more than 9,000 feet below Everest's peak. Once you enter the Khumbu Icefall, which is just above base camp, you're likely fucked if anything goes wrong.
Read the article and propose your solution since, in your mind, it seems to be an simple solution. Be sure to include how you would get a frozen body across a bunch of these crevasses in the icefall while laboring for breath at nearly 18,000 feet.
"Clear weather on Monday allowed helicopters to reach altitudes of 20,000 feet and pluck stranded climbers from high up the mountain, Agence France-Press reported. Because of thinning atmosphere at that high altitude, each aircraft could only evacuate two people, Romanian climber Alex Gavan said on Twitter."
