“Reb Chaim absolutely did NOT call those who violate the heath ministry�s rules rodfim”
he did.
In point #2
“A person who claims that he trusts in Hashem that he won�t become ill and therefore he makes light of the health ministry�s instructions (keeping a distance from others, not leaving the home unless it�s urgent, etc.) can he be defined as a �rodeif� because he�s liable to endanger others?”
I cant be bothered to retype the hebrew but the above is a fair translation of point #2
(you are right about the informing part which was regarding a person violating quarantine)
