If you accept the premise below (which I don't) do you believe in original sin?

Premise - even if you are vaccinated you must wear a mask around other people or you are selfish and don't care if they die

In the absence of mask mandates I have noticed most people in public, whether indoors or out, do not wear a mask. Does this mean most people are selfish and sinful? If you believe this, do you find it evidence of original sin?
