The poem says rizal and the other heroes cannot rest yet why are they still need?

In the context of the poem, José Rizal and other heroes are depicted as restless spirits who cannot find peace in the afterlife because their work remains unfinished. They are still needed by their nation to inspire, guide, and lead the people in their struggle for freedom, justice, and progress. The poem suggests that the heroes' sacrifices were not in vain and that their legacy continues to inspire and motivate future generations. They serve as symbols of hope, courage, and determination, reminding the people of their duty to fight for a better future for themselves and their country.
