Choosing a topic for essay on LOTF

Hello all and great forum. First post here so be nice lol.Our teacher has assigned an essay on the lord of the flies. We have to form our own thesis' and he has given us topics for guidance. I'm having a little trouble choosing a topic and was hoping to get a second opinion. Here they are, and thx for any advice.

1.) Lord of the Flies as a moral allegory.
-he wants us to choose a character and develop him as a symbol of moral allegory

2.) Ralph and Jack and their leadership styles.
-identify the 2 styles of government (democratic & totaltarian) then relate to world and world
progression (I like this topic but I need a bit more consultation with prof)

3.) The use of the mask in LOTF
-identify it's symbolism and it's progression

4.) Jack as a Lucifer figure.
-how Golding uses the story of Lucifer in the bible to show Jack's attitude (it's a great topic for
me but I'm afraid I might be a bit too repetitive and have problems with quoting the bible

5.) Fear is the enemy of civilization and prevents construction and progress.
-pretty much given thesis but I'm not sure how to narrow it down

7.) Golding disagreed with Jean Jacques Rousseau who suggested that man was essentially, by nature, good and that it was society that corrupted the noble savage. (I might have trouble narrowing this one too)

If anyone could help grow on the topic as far as narrowing it down goes, that would be most appreciative. Recommendations would be great with reasoning. Thx a lot for reading.
