In The Lord of the Flies, Jack was a powerful representation of the evil instinct of all humankind and society due to his desire to have power and authority, his thrill for violence and "bloodlust" that evolved from his growing savagery, and his inability to control the evil instinct or darkness of a man's heart. From the beginning the novel, Jack was seen as a leader of his choir group. They were very well trained and obedient to him. It was obvious that he enjoyed the ability to have control over them. Every action taken by the group was commanded by him, even the smallest detail like moving around or taking off jackets. But when Ralph was chosen as the leader for the entire group, Jack was "under a blush of mortification" (23). As of that point on, Jack began to crave for power. Moreover, it wasn't merely a search for a dominant supremacy. Jack's envy for Ralph was the fodder that kept his fire blazing. Then as he began to build up that control over the boys by the blood of pigs, he needed to feel more and more of that power. After another victorious kill, he cries out, "I gave you food, and my hunters will protect you from the beast. Who will join my tribe?" (150). The accomplishment of feeding an entire group of boys with meat was a sufficient reason for him to now take over the whole group, which he eventually achieved. .
The violent, hostile, and menacing part of him also commenced to enlarge as a more intensified state that was almost incontrollable. From the actual moments of slaughter to the reenactment of the gruesome killings, and then to the chants and dances, Jack, above all, found thrill and excitement from each experience. The blood of the pigs on his own hands and body enlivened his emotions. Yet the first attempt at murdering the pig was unsuccessful because of the remaining bit of humanity in Jack. On account of that, Jack wanted to prove even more that he was able, and that he had the power to accomplish the deed.
