I don't see what the problem is. The surgeons obviously aren't crackpots. In fact they're accomplished surgeons. The man isn't asking for assisted suicide, he's asking for a chance to save his life.
What gives anybody the right to deny him this chance at saving his own life?
Just think what a surgery of this nature could do for humanity if it's successful. How many diseases, accidents, major birth defects could be fixed with this type of surgery.
I pray that the Lord guides those surgeon's hands so they can indeed save his life.
