How appropiate is Scout as a narrator for a Southern Gothic novel like To Kill a Mockingbird?

A key element of the Southern
Gothic tale (unlike the traditional Gothic story) is that it reveals the
horrific or grotesque through traditional Southern American issues such as slavery and
racial bias.  Rather than dark and remote settings, atmosphere containing mostly bad
weather, or the presence of the super-natural as a demonic element, the Southern Gothic
reveals the "horrific" or "grotesque" situations of America's history.  This is done
through characters who possess blatant bigotry and egotistical
self-righteousness.

Scout, as the narrator of To
Kill A Mockingbird, is presented as young and innocent, but by no means
ignorant.  In fact, she is expected to be ignorant because she is
young, but do not forget the narrator is the adult Scout, looking back.  In this way,
the young Scout is privy to several key pieces of information (especially character and
situational nuances) which the adult Scout presents without bias.  In this way, Harper
Lee manages to reveal several instances of social prejudice and injustice without
sounding preachy nor tolerant.  This balance is created through Scout's childlike
honesty and ability to tell things as she remembers them.  It often comes across as both
humorous and pitiful.
