In Lord of the Flies, how do Piggy's and Ralph's reactions to Simon's death differ?

reacts to 's
death with candor, whiletries to rationalize what has happened.

Having
communicated with the , Simon felt that he must carry his news that the beast is within to the
others as soon as possible. So, he came out of the clearing and down to the fire where the other
boys were gathered. 

Just before Simon arrived,mimicked the grunting and
charging of the pig;ran excitedly around the perimeter, and Ralph and Piggy themselves became
eager to have a place in this group. Roger left the circle to be the hunter, chanting with the
others. As he did so "there was the throb and stamp of a singular organism." The boys
did not see clearly and they envisioned 

...a beast [who]
struggled forward, broke the ring...screamed something about a body...

These boys became a "struggling heap," and finally they
broke up and moved away as blood stained the sand. They ran in terror as the wind caught the
parachutist and they watched as his figure was thrown upon the sea. Later, the tide carried
Simon's body out to sea.

The following day, Ralph is prepared to admit that
he has been in that circle and has contributed to the death of the boy who came to warn them:
"Piggy.... That was Simon." But Piggy is in denial:

"You stop it!" said Piggy shrilly. "What good're you doing talking like
that? ... It was dark. There was that--that bloody dance. There was lightning and thunder and
rain. We was scared."

"I wasn't scared.... Don't you understand
Piggy? The things we did--" 

"Look, Ralph. We got to forget this.
We can't do no good thinking about is, see? ... It was an accident, and that's
that."

Despite his insistence that what happened to
Simon was an accident, Piggy acknowledges that they need to be rescued and "get out of
this" lawless world in which they now live.

Ralph gives in and tell
Piggy to try to forget the whole affair since they cannot do any good by thinking about it. But
the air is heavy with the unspoken knowledge of what man is capable of, and they shake at the
horror of what they have done.

Both boys realize what has become of them and
their reasoning and gentler natures. They are desperate to be successful in their attempts at
flight.
