The single simplest summation of the concept of evil is "the end justifies the means".
That's a rather strong way to describe someone who refuses to implement a policy you like.
You might be right, a natural immunity exemption might be sound policy. I personally tend to agree. But you can't make the case for it by pretending that opposition to it is based in ignorance or evil, if the opposition is due to the concern that people who would abuse it and the result would be more deaths.
Vaccine mandates are now down the path of forbidding us to choose what we do with our own bodies.
This is a very, very dangerous path.
Punishing nurses that have aquired immunity via natural infection will hopefully be considered criminal in a not too far away future. Fortunately there are very few places in the world that thinks that doing so is a good idea.
For you perhaps, but some people have the terminal goal of avoiding vaccination, even if that increases the threat. That is why the government is doing anything and everything, including FUD, to push vaccines down peoples' throats. Their actions will always seem irrational if you ignore that.
