I find it weirdly and uncomfortably bothersome when unvaccinated people post condolences about COVID deaths. Not to say they're not bothered and upset by the death, but what do they think caused and perpetuated it? Something other than the COVID, from which they choose to stay unvaccinated? 

If after seeing other people they know (or family members or friends of people they know) die from COVID, they STILL don't bother getting vaccinated, what does that mean?

Is it because they think COVID can't affect them or they think the vaccine doesn't work (or has deadly side effects)?

Or because they tell themselves that all the people who die from COVID are old weaklings who were going to die anyway?

Or because they're too lazy to think and plan until something bad actually happens to them (and maybe still too lazy to think and plan even after something bad actually happens to someone they know)?

Or maybe they just don't really care? 

Of course everyone is going to die at some point, but who wants to die from something that could have been prevented (or made significantly milder) with a vaccine?
