Kim, the reaction of the very religious doctors to avoid discussing options to "help hasten the end of life for their patients" is certainly consistent with surveys which found that the more religious patient will avoid a premature death and look for a miracle in their final days of illness and request more tests and treatments despite their therapeutic futility. A good review of one such study written in the Journal of the American Medical Association from the Dana Farber Cancer Institute can be found in the ABC News site:

As I have said, physician's instilling their own religious views into the decisions to be make by their patient's is unethical. Also unethical in the doctor-patient relationship would be for the doctor to ignore to present to the patient some option which others have taken but which is against the physician's own moral and religious values. Instead such a religious physician could and should frankly tell the patient about the option which has been used by others but the physician can tell the patient that if the patient selects such an option, the physician could not participate and would try to find another physician who would agree with the patient's decision.
An answer to the conflict between the patient and the doctor in terms of religious values, as I may have written elsewhere, is one presented in the past by ethicist Robert Veatch who appears to encourage patients to attempt to select their physicians, if possible, with the same religious values as their own. Certainly, however, it would be appropriate at some point in the doctor-patient interaction but while the patient is still healthy, for the patient to bring up end-of-life issues with their doctor and try to understand their physician's views. This would be particularly important if the doctor failed to bring up the issue earlier.
On an upcoming Question, I would like to bring up the issue of alternative models of doctor-patient relationships including the listing of Robert Veatch's models. ..Maurice.
