Ignoring any Secular law issues,
Is a Jew obligated to save the life of a wicked non Jew? Does it make a difference whether his refusal will become publicly known?
If a non-Jew who is a rasha got cancer and went to a Jewish oncologist then may the oncologist refuse to treat him? Is there an obligation for the oncologist to treat the non-Jew or an obligation to refuse him treatment? What is the halacha on this?
