I'm not excusing their behavior, but it's worth keeping in mind the context. They have an extraordinarily risky job that they are not paid much for, compared to the people who pay them. See, for example, https://www.washingtonpost.com/news/worldviews/wp/2014/04/21/a-closer-look-at-the-dangerous-work-that-everests-sherpas-undertake-for-western-climbers/ https://www.washingtonpost.com/news/worldviews/wp/2014/04/21..., but googling around is easy to find other articles from other sources talking about the high risk and low pay for Everest Sherpas.
