First of all, to answer FrumRoshYeshivas question: In WW2 and the Inquisition it was shas hashmaad. Unless you are a serious conspiracy theorist i don’t think the rules against gatherings were designed by the CDC specifically to stop minyanim.
additionally, in those cases it was yechidim giving up their own lives, that we call moser nefesh. In our cases it’s yechidim giving up other peoples lives, that’s called a (safek) murderer.
(and i don’t believe you to actually be a standard rosh yeshiva)
In response to the original topic I’d like to suggest the following.
The jews who are violating the stay home orders can be broken up into 2 groups, 1) those without internet and don’t really have a grasp on how many niftarim there have been (obviously 99.88% of those without internet are following instructions) and 2) those who don’t have trust in authority and aren’t thinking clearly.
Both of these groups, if they would realize what they are doing would immediately stop.
The majority Non-Jews who aren’t following the instructions hwever, to my belief simply don’t care. That is the difference between us and them.
Disclaimer- I don’t believe that lack of internet is a bad thing, but this is a side-effect of it.
