In chapter seven of Lord of the Flies, there is deterioration of democratic rule. Although everyone voted for Ralph to be the leader early own, Jack has become power hungry. He has become savage in his actions. He will stop at nothing to gain absolute control over the boys. The longer they are on the island, the farther the boys drift from democratic rule:
One progression highlighted in this chapter is the boys’ increasing loss of identity. The longer they remain on the island, the farther away from their civilized selves they move.
In chapter eleven, when Piggy is killed and the twins are tied up to gain power over them, Jack is in total control. He will stop at nothing to become a tyrant over all the boys. Anyone who tries to stop him will be tortured or killed. The reader learns that Ralph's attempts at a democracy ended with Piggy's death. There is no one on Ralph's side now.
By the end of the novel, Jack declares himself chief, claiming that Ralph will get what happened to Piggy:
Jack screams that that’s what Ralph will get. The conch is gone. He is chief now. He hurls his spear at Ralph, grazing his side. The others, including Roger, hurl their spears as well. Ralph turns and flees...
Fortunately, Ralph runs into the naval officer. Jack has become so blood thirsty until Ralph would have been killed by Jack and his savage followers. Everyone had abandoned the democratic rule for Jack's absolute control.
Jack and his savagery had consumed the boys. Only Ralph still believed in democratic rule.
