PLAYING GOD? Are you freaking kidding me? That argument went out the window the minute man started practicing medicine. We play God EVERY SINGLE DAY and you know it.
When I was seven I was in a very serious accident which required me to be hospitalized for several months. When my parents couldn't be at the hospital, I had very little stimulation or interaction with other people. I laid in bed and developed blood filled sores all over my legs. I couldn't wait to get out of the hospital. When I did finally get home, I was in a full body-cast and even though I was a little girl, it was quite a chore for people to lift me. If I had been older when the accident happened, my parents definitely would not have been able to care for me the way they did -- surrounded by friends and family and not strangers.
It's easy to say what you would do or would not do in this situation until you are actually in it and have to make tough choices.
