Towards the end of the story, both Jack and Ralph meet atop of Castle Rock and begin to quarrel: "Jack made a rush and stabbed at Ralph's chest with his spear." (Golding 196) From this passage, Jack not only rushes at Ralph with his spear, but he also aims for a fatal stab at Ralph's chest. Without doubt, the spear that Jack constantly uses on the island greatly contributes to his aggressive and violent actions that he commits throughout the novel. Particularly, these violent and ruthless actions that Jack consistently commits is only possible through the face paint that he wears to mask his innocent, civilized nature.
Another symbol that develops Jack's character is the face paint that he wears, which symbolizes his emerging evil persona and represents his submission to a primitive and savage way of life. Initially, Jack tries to justify his intentions for the use of the face paint as camouflage. Instead, he begins to wear it as a protective mask, in which he uses to hide behind. Shortly after Jack looks at his new and compelling face paint, he unknowingly reveals a hint of his darker and uncontrollable personality: "He began to dance and his laughter became a bloodthirsty snarling. He capered towards Bill and the mask was a thing on its own, behind which Jack hid, liberated from shame and self-consciousness" (Golding 66). This passage indicates how the mask is actually a thing on its own, which specifically promotes it as an important and fundamental aspect of Jack's dark and evil persona. In the meantime, Jack truly begins to depend upon the protective mask and starts to use it as a shield to liberate himself from any kind of shame, guilt, or self-consciousness.
As Jack goes on to viciously hunt on the island, it becomes more apparent that his thought of civilization is rapidly diminishing.
