Can I get a quote about Piggy explaining how he is a tragic hero in The Lord of the Flies?

I would want to argue that a great quote you could use
would be the final quote refering to Piggy in the novel, which comes when Ralph sees
that delieverance has at last arrived and that the boys are rescued. Note how Ralph
reacts to the sight of the naval officers who have come to take the boys
away:

And in
the middle of them, with filthy body, matted hair, and unwiped nose, Ralph wept for the
end of innocence, the darkness of man's heart, and the fall through the air of the true,
wise friend called
Piggy.

Note the way that
Piggy is described in this important quote. He is a "true, wise friend," whose death
exemplified what Ralph has learnt about the "end of innocence" and "the darkness of
man's heart." It is clear therefore that he has heroic qualities, in the way that he
remained loyal and true to Ralph up until his death, and that his death was heroic in
the way that he tried to challenge the mob and reason with them, bringing them to their
senses. The way in which he failed of course symbolises the triumph of savagery over
reason.
