I think there's a difference between choosing whose lives have value and choosing who to empathize with. I'm not celebrating their deaths, but aside from the teen who was on there, I can't say I feel much about it one way or another. They knowingly chose to take the risk, signing waivers saying that they knew the trip could result in death, and it ended badly.

Looking at it from a different angle, I can also see why people would be frustrated that an incredible amount of attention and resources are being spent on people who intentionally put themselves at risk for a pleasure jaunt, while if a fraction of that (on a per capita level) was spent on everyone who was at risk of dying from issues brought on or exacerbated by poverty, we'd be saving a lot of lives.
