If you're going to feel bad for them then you should also feel bad for the climbers, and vice versa.
I don’t think so. This is an asymmetric relationship. It’s been documented time and time again the tourists treat the sherpas like shit. There’s also plenty of evidence they treat the mountain like shit, a mountain which is sacred to the Sherpa people. No, I don’t think I’ll feel bad for those who litter in what should be a pristine location and treat the locals poorly.
(Side note, I don’t even know what to call that extra vice versa. It’s like a vice versa double negative. You were already in vice versa mode by suggesting I should also feel bad for the tourists.)
