The savior Naval Officer pretends to not understand the murderous intent of the boys because he needs to save not just Ralph, but Jack and all the other boys. The irony lies in what the Naval officer is saving them for. Who is William Golding who is obvious the Naval officer? Golding was a Naval Officer who had trained boys to be killers and to be killed in World War II. So the Naval officer is saving Ralph from being killed and is saving these murderous boys to be just boys again, so that they can be later trained as killers and potentially be killed in the future WW II.
