This is greatly exaggerated. She worked in areas with undertrained nurses trying to treat people with little resources. Hospice and care for the dying gets messy. In our society elder abuse in care homes is as regular as clockwork. I don't see the purpose of being obtuse about the nature of life and disease outside of the first world. For many people life has much suffering, and the best you can do is help to comfort them and give their suffering meaning. It's easy to poke holes in things, but again it's not as if our currently accepted medical system is perfect. We have better standards of healthcare for those that can afford it, but the rest are on their own.
