In regards to the last scene in Lord of the Flies where the naval officer is talking to the boys, what does William Golding think of humanity?

At the end of the novel, as Ralph is running for his life from Jack and his tribe of savages, he surprisingly encounters a British naval officer who is standing on the beach. When the band of savages follow Ralph onto the beach, they stop and stare at the officer. The officer assumes that the boys are playing a fun game, similar to the adventures that take place in the story Coral Island. After Ralph is unable to tell him how many boys are on the island, the officer comments, "I should have thought that a pack of British boys—you’re all British, aren’t you?—would have been able to put up a better show than that—I mean—" (Golding 201). The fact that the officer is oblivious to their current situation and is judgmental, reveals his hypocrisy and ignorance. The naval officer is currently participating in a World War which is equally as savage and barbaric as the events that took place on the island among the group of boys. Golding is suggesting that humanity is inherently evil, and the decay of civility on the island is essentially a microcosm of what happens in the outside world. The children, like Adam and Eve in the Old Testament, were given an opportunity to create a civil society which eventually was destroyed.
