I just don't think that's the only alternative. There must be some other way. Being a doctor isn't like being a stamp collector. You dont just quit. I must admit, I don't have the answer, but quitting has to be a last resort, not the first.
Being a doctor is no better or worse than any other job. You don't murder people. It is not extreme to refuse to or to refuse to work in a system that makes murder required or even practiced. Quitting being a doctor beats joining being a murderer in my mind any day. I don't get why any doc would practice in any place where murder was even encouraged.
