During Simon's encounter with the Lord of the Flies, the Lord of the Flies says:
“You knew, didn’t you? I’m part of you? Close, close, close! I’m the reason why it’s no go? Why things are what they are?”
I understand the general idea of the sentence, that Simon is the only one who realizes that the Beast is inside the boys, but why are there so many question marks? It makes sense for "You knew, didn't you?", but for "I'm part of you?", "I'm the reason why it's no go?", and "Why things are what they are?" it seems odd.
Does anyone have an idea as to why Golding included these?
