Whatever the situation is or is not, may this child have a refuah shelaima b’soch sh’or cholei Yisroel. Let’s not quibble, but better, use the time more productively to daven for someone else’s child, who needs a refuah and yeshua b’korov.
Even if the biggest rasha were to be the vehicle through which Hashem decides to help someone (meaning, that because of this doctor, people’s awareness of the situation is greatly raised and perhaps another doctor then could step in, or something like that), then it is worth it. In any case, I am sure the RBSH”O will make His cheshbonos about the doctor. I hope this little boy’s life is spared. I cannot imagine the pain his family is going through, and we have something similar going on with people very close to me now, so I am wholly empathetic to the need to find refuos out of the thin air. Please, let’s not argue about this amongst ourselves. Our opinions are not the important issue right now.
