* Desire for control: Both characters crave a sense of control and power. Jack seeks it through brute force and manipulation, aiming to be the leader of the pack. Piggy, on the other hand, desires control through intellect and reason, attempting to establish order and a sense of civilization.
* Need for belonging: Both characters are deeply affected by their experiences on the island. Jack seeks belonging through the tribe and its primal urges, while Piggy craves belonging through intellectual connection and the shared knowledge of the group. This need for belonging is evident in Piggy's desperate clinging to the "grown-up" world and his connection to Ralph.
* Vulnerability: Both characters are ultimately vulnerable. Jack's reliance on the tribe's approval and his fear of losing power show his fragility. Piggy's intellectual superiority and physical weakness make him vulnerable to the savagery of the island.
While their methods and perspectives differ dramatically, both Jack and Piggy are ultimately driven by a desire for control, a need for belonging, and an underlying vulnerability. This shared humanity, despite their contrasting approaches, makes them complex and relatable characters.
