I question the wisdom of belief in the existence of the devil - at least in a form that can be beaten to death. "Ultimate evil" and "susceptibility to haymakers" seem mutually exclusive. This sounds more like the confluence of blind hope that cosmically-horrifying things can be defeated and rationalizing murdering another person.

In the particular case of Perelandra, without too many spoilers, the devil possessed a man from Earth and was using him to try and tempt the Venutian equivalent of Eve into causing another Fall. How sometimes killing evil instead of arguing with it might apply to more practical religious and moral situations in real life is left as an exercise to the reader.
