The purpose of Jack’s generosity
with the meat was to gain control over all the boys in the group and persuade
all the other boys who aren't already with him to join his group. He pretty
much achieved his aim but he still wasn’t able to win over Ralph and Piggy to
his group. His decision to give the meat to even Ralph and Piggy is meant to
show the boys that he is a benevolent leader who will be generous even to
people who do not belong in his group.
