Explain why Tubman feels she must act this way?

Harriet Tubman felt compelled to act decisively in her efforts to lead enslaved people to freedom due to her deep conviction in the moral imperative of liberation. Having experienced the brutal realities of slavery firsthand, she recognized the urgent need to escape and secure freedom not only for herself but for others as well. Tubman's resilience and determination were motivated by her belief in justice and the fundamental right to live freely, which drove her to risk her life repeatedly on the Underground Railroad. Her actions were fueled by a combination of personal experience, empathy for her fellow enslaved individuals, and a commitment to social change.
