I'd say that every situation of emergency, as a pandemic could be, tend to exacerbate a high number of naturally occurring tendencies, among which moral ones. Let's say if you normally don't care about others, hardly a situation like the one we're facing would prevent you from keeping on engaging in this careless behavior. Conversely, if your moral values are resonant with those that Haidt and colleagues call "Harm" and "Fairness" domains, you won't reduce your interest in caring about others due to the pandemic; on the contrary, you'll tend to be more worried. My two humble cents in a not-too-scientific fashion.
I think humanity has failed to some extent in the covid challenge. We did not witness any emergency plans headed by the UN, nor the security council took courageous steps to minimize the UN sanctions on particular countries nor to left unilateral sanction. Even on the regional levels, no energy campaigns were launched to help undeveloped countries. also on the spiritual level, it is so strange that none of the international religious institutions (like the Vatican, Azhar al sharif..) held public prayers so humanity can recover from this pandemic crisis.. it seems there is a value crisis as well!
