Ralph has the personality of the "reluctant leader." Piggy, as the "brains of the operation," sees in Ralph the qualities that he (Piggy) knows to be crucial for effective leadership. Qualities that he (Piggy) does not possess. These qualities include communication skills, what we might today call "telegenic charm," and the abiltiy to summon others through the use of the conch. The conch is seen by others on the island as a symbol of authority. Ralph has the physical ability to blow into the conch, but it takes Piggy's know-how for the conch to be used.
In a way, Ralph is sort of thrust into a position of leadership. Piggy sees in Ralph the boys' best hope for survival. Perhaps Ralph's personality is latent. Whatever the case, it begins to assert itself through their collective needs. And it is these needs that Piggy helps Ralph to realize.
Ralph is the athletic, charismatic protagonist of Lord of the Flies. Elected the leader of the boys at the beginning of the novel, Ralph is the primary representative of order, civilization, and productive leadership in the novel. While most of the other boys initially are concerned with playing, having fun, and avoiding work, Ralph sets about building huts and thinking of ways to maximize their chances of being rescued. For this reason, Ralph's power and influence over the other boys are secure at the beginning of the novel. However, as the group gradually succumbs to savage instincts over the course of the novel, Ralph's position declines precipitously while Jack's rises. Eventually, most of the boys except Piggy leave Ralph's group for Jack's, and Ralph is left alone to be hunted by Jack's tribe. Ralph's commitment to civilization and morality is strong, and his main wish is to be rescued and returned to the society of adults. In a sense, this strength gives Ralph a moral victory at the end of the novel, when he casts the Lord of the Flies to the ground and takes up the stake it is impaled on to defend himself against Jack's hunters.
In the earlier parts of the novel, Ralph is unable to understand why the other boys would give in to base instincts of bloodlust and barbarism. The sight of the hunters chanting and dancing is baffling and distasteful to him. As the novel progresses, however, Ralph, like Simon, comes to understand that savagery exists within all the boys. Ralph remains determined not to let this savagery -overwhelm him, and only briefly does he consider joining Jack's tribe in order to save himself. When Ralph hunts a boar for the first time, however, he experiences the exhilaration and thrill of bloodlust and violence. When he attends Jack's feast, he is swept away by the frenzy, dances on the edge of the group, and participates in the killing of Simon. This firsthand knowledge of the evil that exists within him, as within all human beings, is tragic for Ralph, and it plunges him into listless despair for a time. But this knowledge also enables him to cast down the Lord of the Flies at the end of the novel. Ralph's story ends semi-tragically: although he is rescued and returned to civilization, when he sees the naval officer, he weeps with the burden of his new knowledge about the human capacity for evil.
