I'm not so sure they're not comparable, they certainly seem to at minimum be a gradient of the same curve. "Unnecessary deaths" is a tricky thing to attempt to claim, and you'll need a bit more than shouting into the void to back such a claim up. Indeed you'd need some pretty detailed analysis to claim an unusual number of deaths directly attributable to a lack of available care at facilities typically able to provide said care, specifically because they simply didn't have the resources to administer the care. In other words, I doubt your latter scenario at the more extreme end of overloading was widely the case (in the first world), perhaps you have some analysis backing it up?
