This is an arbitrary goal post. There need not be any secret motive of the county officials to make their reasoning incorrect or the law not right. Their motives could be completely public and still scrutinized and found to be incorrect.
I think that they intend to save lives but that their understanding of the SARS-CoV-2 pandemic and the best way to address it is so overly simplistic that the myopic policies they are instituting are going to lead to larger mortality over the long-term. Which is the pattern we see at the broader scale as well when we examine the US' response to the pandemic.
So, like I implied above, their intentions are good, but intentions are largely worthless.
