I don’t know why you think people cannot be blamed for the role they choose to have in society. That’s very weird. And if that’s not the point you’re trying to make I’m not sure what it is.
Our society specifically allows (and maybe even facilitates) public health insurance companies that can deny terminally ill people the care they need. If someone chooses to step into that job, I can’t blame them from a legal standpoint. I can blame them from a moral one, but the laws of morality do not guide our country, sadly.
