It's not hard. I don't know why you wrote all these unrelated questions. This is simply about direct personal injury from COVID infection caused by those who took no mitigation steps to prevent harm to others(COVID specific harm). They should be held liable like any other personal injury or wrongful death due to gross negligence. Simply a matter of taking individual responsibility for your individual choices. Do we actually do this? No. Unvaccinated get a special waiver to not be held accountable for their actions. All the freedom, none of the responsibilities or accountability for their actions. That is quite selfish and entitled.
