I agree. At least I've got very mixed feelings here.
If I lived in that community, my daughter would have died, and it would have been a horrible death. Modern medicine and complex surgeries saved her. The idea that she'd have been condemned to death, without even being aware that she could have been saved is awful.
Then again, would I have even had her? Vision problems mean that I'm pretty much partially sighted without glasses. I wouldn't have been able to work, would struggle to safely raise kids, cook independently etc. What sort of life would I have had without glasses?
Equally, the death rates from viruses brought in is seemingly horrific and that outweighs everything I've put here really. There's no point saving people from curable conditions if you kill most to begin with.
