Why is John Brown against slavery?

John Brown was against slavery due to his strong belief in equality and justice, viewing slavery as a moral atrocity that violated the fundamental rights of human beings. His fervent abolitionist stance was influenced by religious convictions and a deep sense of duty to fight against what he saw as an evil institution. Brown believed that direct action, including armed insurrection, was necessary to dismantle slavery and achieve freedom for enslaved people. His commitment to this cause ultimately led him to take extreme measures, including the raid on Harpers Ferry.
