There's an undercurrent of baseless entitlement to whatever can be got for nothing, which is a core belief of people who just believe they're victims of whatever they seem to think they should have, when there are 'haves and have-nots'.
Once a cause is recognised, like - say - a benefit in kind, or monetary, the entitlement manifests itself in a false sense of appropriate receipt, whether it is earned or un-earned.
This feeling of 'justification' for whatever the recipient of such largesse suggests that they have a totally unrealistic view of how to proceed when others are trying to run the same scenario.
Thus, when someone is unfortunate, the original 'victims', who have produced a 'result', decide to vilify others in diverse ways, deciding that they are better than the rest, and believing that they are being righteous in putting down 'lesser' mortals, who are still suffering, nonetheless, but the original victim will really think he is winning the fight - albeit subject to a simple fallacy in his own mind.
Thus, someone who is unfortunate enough to contract such an affliction as a serious disease, or a virus, such as Covid 19, is judged to be 'inferior', and often seen as a threat, hence the insulting, anonymous indignation displayed by the said original victim. It is thoughtless, full of reverse envy, and unsubtle, but twisted, bitter and usually the aspiration of an unreasonable, probably unrealistic, and under performing person.
He knows that nobody will attack him personally, so hides behind these 'threats', and continues a smug existence, thinking he has achieved something, which to most normal people, isn't the case.
It's so easy to be a victim these days, blaming just about everyone and everything for their own failings, but not being too bright on the subject, it's an easy aggressive technique with no fear of reprisal!
