William Golding warns people against the practice of evil doing. Discuss.

I have to agree with the previous poster, particularly if
you look at the way Simon, arguably the most insightful member of the group of boys,
eventually figures out that the "beast" is actually the evil that is within the boys
rather than some external creature or parachutist or whatever else.  The fact that
Golding gives Simon this realization and then Simon is killed immediately thereafter
serves only to emphasize this discovery.

As such, Golding
is really pointing out the danger of that evil within us and the fact that without some
constraints, it can lead us to do things that are rather
terrifying.
