I'm curious. Do you think that if your grandmother had more wealth, then she'd be able to walk with less pain? Or is it a case where the treatment/cure might be worse than the disease?

It's very immoral to allow (force) people to die, when they otherwise could live if they have more money.

It's less egregious, but still immoral to allow (force) people to live in pain.

I think it is a much more complicated issue to balance medical "expertise" with patient desires. If your grandmother wants a treatment and her healthcare providers believe she should not have it, not because it affects their profits, but because it's medically ill-advised, then what?
