In what ways does Lord of the Flies reflect real life, and in what ways does it not?What passages and particular details support the answer?

As the novel Lord of the Flies ends
with the naval officer, a commander in a war that involves savage acts, appearing as the
representative of civilization that has arrived to save the boys, it is dubious if
Golding believes that civilization can control the inherent evil in man, or that
anything,for that matter, can control the evil men
do:

"Fancy
thinking the Beast was something you could hunt and kill!" sid the head [of the pig]. 
For a moment or two the forest and all the other dimly appreciated places echoed with
the parody of laughter.  "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?"

Golding tells the
reader in his allegory that the evil in man in innate.  Whether in civilization or on a
paradisaical island, this inherent evil emerges.  The arm of Roger has merely been
controlled by civilization--

Roger's arm was conditioned by a civilization
that knew nothing of him and was in
ruins--

his arm has
conditioned, but civilization has not eradicated the evil from Roger.  Removed from the
conditioning, the sadistic nature of Roger is given full rein and he picks up the
stone,"that token of preposterous time," and throws it at innocent little Henry by the
seaside.  The evil was always present in Roger.  Even Ralph possesses this evil.  In
Chapter Two as he realizes that the boys fall still and
silent,

he
feels awe at the power set free below them.  The knowledge and the awe
made him
savage.

Of
course, later on when Ralph participates in the hunt, he becomes rather savage then,
too.  This is why he cries when the officer appears, for he "wept for the end of
innocence" as Jack

starts forward, then changed his mind and stood
still.

Even as the officer
turns away for the boys to recover themselves, he allows his eyes to rest upon the trim
cruiser in the distance, a symbol of war, with its death and savagery, an action that
reflects man's intrinsic nature. This portrayal of the inherent evil of man is Golding's
allegorical way of reflecting life.  Art does, indeed, imitate life in Lord of
the Flies.
