What does Simon's treatment of the parachuist suggest?

In Chapter 9 of Lord of the Flies,
Simon awakens from his seizure and attempts to return to the others.  As he struggles
through the creepers a "buffet of wind" causes him to stagger as his legs are weak and
he is in pain.  When the wind touches the mountain-top, Simon sees "a humped thing
suddenly sit up on the top and look down at him."  With flies on it and the "colors of
corruption" upon the rotting figure, the already weak Simon kneels on all fours and
vomits.  But, he is able to take the lines of the parachutist and free it from "the
wind's indignity."  This action suggests that Simon is sickened by the sight of the
evils of war and the destruction that it brings to man.  In an effort to free the spirit
of the man who was once the parachutist, Simon releases the body from the confines of
nature and the earth.
