To me, they were people doing a super risky thing who died doing that risky thing. It's a shame, but they made the choice to do that super risky thing.
What annoys me is the "privatize the wins, socialize the losses" aspect. I'm pretty sure these guys weren't paying any taxes to Canada, but it's Canada paying for the search and rescue operations. Making it extra galling is that the owner cut corners, presumably to increase profits. Sure, high profits hopefully means high taxes somewhere, but even at $250k/pop the profits would never be enough to pay for the Search and Rescue efforts that that corner cutting was going to eventually require.
