This perp needs to be castrated all the same. With a red-hot, and rather blunt, knife. He is simply bad news waiting to become worse.
Hey Tiger Woods can drive a ball about 300 yards. Forget the hot knife, Give Tiger a Big Bertha, and let him take a whack at it. I imagine after the guy wakes up he won't feel like eating much, and that things will be swollen sore.
