Why do all the boys resign from Tom's gang?

All the boys resign from Tom's gang because they become frustrated with Tom's leadership and his tendency to make decisions that don't consider their interests. Tom's constant excitement and impulsiveness lead to dangerous situations that the boys find unappealing. Additionally, his desire for adventure often overshadows the group's sense of camaraderie, prompting the boys to seek more reliable and enjoyable activities elsewhere. Ultimately, they seek a more stable and enjoyable environment, which Tom's gang no longer provides.
