What are some dominate personality traits of Simon in the novel Lord of The Flies?

One of the main traits is that Simon is compassionate and
very caring.  He is really the only boy that does not appear to take sides when it comes
to Jack or Ralph and he also makes it very clear that he cares for the littl'uns in a
way that the others do not.

He also has a very serious
introspective streak as he thinks carefully about what is happening and ends up being
the only boy to figure out the real nature of the beast.  He is very sensitive, not only
to the boys but also sensitive enough that he cannot even handle the vision of the beast
and he passes out after the experience.
