In John Milton’s epic poem Paradise Lost, Satan is cast out of heaven primarily for his rebellion against God. His pride and ambition lead him to challenge God’s authority and seek to overthrow Him. This act of defiance is considered the original sin, as it stems from Lucifer’s desire to be equal to or greater than God, which is a direct violation of the divine order.
The poem illustrates Satan’s transformation from Lucifer, a once-beautiful archangel, into a vengeful and malevolent figure. His desire for power and autonomy ultimately results in his expulsion from heaven, symbolizing the consequences of pride and the rejection of divine hierarchy. Milton crafts this narrative to explore themes of free will, obedience, and the nature of evil, making Satan’s fall a profound commentary on the complexity of sin and the fall of man.
