A baby boy was born in Brazil with two heads. Should doctors remove one head?

When I first observed this photo on Yahoo News. I was shocked. I have seen animals with one body and two heads, but never a human. Both heads share one body’s functions. Doctors are trying to determine if they should decapitate one head, so the other can live a normal life. Question: if you are the surgeon set to remove one head, how would you prepare yourself for this ordeal and could you live with yourself, afterwards?
