What are Ralph's and Jack's objectives in Lord of the Flies?
Ralphs over riding objective is for them all to be rescued. Jack has two main objectives, to be the person in charge and to kill pigs.
By creating a set of rules. After Ralph become their leader they create a set of rules, what/where the lavatory is, building shelters, fetching food, lighting the fire (fighting for rescue). This diminishes fast though. Also Ralphs group after the boys split combs their hair back (society influence tells you to do this) to prevent themselves from looking like jacks group (a pack of savages).
