Kinda. At the end of the book the surviving children are rescued by the captain of a British warship, he berates the boys for acting so "savage", but then look at his warship with pride. FYI it's implied that there's a massive war going on out in the rest of the world during the events of the books. The message is meant to be that civilization is a veneer for humanity's warlike tendencies. Really the ship captain is no better than the boys, he just conducts his slaughter in a uniform. I thought it was kind of clever but the overarching message is mostly just that human suck.
