Satan
Satan, formerly called Lucifer, is the first major character introduced in the poem. He is a tragic figure who famously declares: "Better to reign in Hell, than serve in Heaven" (1.263). He viewed God as a tyrannical figure and refused to be subjected to his reign. Satan was able to accumulate an army of angels who were loyal to his cause. He strove to "set himself in Glory above his Peers," and the pair of "Rebel angels" worked alongside him. Following his vain rebellion against God, he is cast out from Heaven and condemned to Hell. The rebellion stems from Satan's pride and envy, derived from God's proclamation that the Son of God was "anointed" as the saviour (5.660-664ff). As a result, Satan "thought himself impaird", meaning that his envy caused him to perceive himself as being lessened through God's actions.
Satan is also depicted as a persuasive and charismatic being, whose rhetorical skills allow him to manipulate others and rally the fallen angels. What makes him so effective is his ability to "[adapt] his arguments" to suit his needs in any given situation. Some scholars have noted that Milton's use of heroic language, demonstrated in Satan's depiction of having a "fixt mind", "unconquerable Will" and "courage never to submit or yield", contributes to the human-like complexity of his character (1.97, 106, 108). These characteristics resemble an epic hero, but his moral corruption and rebellion undermine this ideal. Satan, due to his own self-deception, spread that same deception to others through manipulation. His actions influence other characters, such as the fallen angels and Adam and Eve, to be coerced into disobedience.
Such actions allude to his use of free will, which is important to his characterisation. Milton portrays his rebellion against God as a deliberate choice. For Satan declares in Book 1 that "in [his] choyce", he would rather have leadership in Hell than Heaven, emphasising that his defying God was personal agency (261). Scholars highlight the fact that Lucifer was not created as evil, but rather, he "consciously" decided to pervert himself despite knowing the consequences out of pride. He maintains autonomy throughout Paradise Lost as he is not compelled to act, but rather plans meticulously for the fall of man and carries it out of his own accord.
Satan's psychological trajectory evolves throughout the poem as his character progresses. Early on, Milton portrays him as a figure of sublimity and a powerful personality, which captivates those who behold him. He presents the qualities of a leader or a great orator. Book 4 marks a turning point in his psyche. Scholars cite Satan's "abjection" as he internally isolates himself from his followers. He laments his condition upon seeing Eden:
Me miserable! which way shall I flie /
Infinite wrauth, and infinite despaire? /
Which way I flie is Hell; my self am Hell;
Opinions on the character are often sharply divided. Milton presents Satan as the origin of all evil, but some readers interpret Milton's Satan as a nuanced or sympathetic character. Romanticist critics in particular, among them William Blake, Lord Byron, Percy Bysshe Shelley, and William Hazlitt, are known for interpreting Satan as a hero of Paradise Lost. This has led other critics, such as C. S. Lewis and Charles Williams, both of whom were devout Christians, to argue against reading Satan as a sympathetic, heroic figure. Despite Blake thinking that Milton intended for Satan to have a heroic role in the poem, Blake himself described Satan as the "state of error," and as beyond salvation.
John Carey argues that this conflict cannot be solved because the character of Satan exists in more modes and greater depth than the other characters of Paradise Lost: in this way, Milton has created an ambivalent character, and any "pro-Satan" or "anti-Satan" argument is by its nature discarding half the evidence. Satan's ambivalence, Carey says, is "a precondition of the poem's success – a major factor in the attention it has aroused".
C. S. Lewis argues in his A Preface to Paradise Lost that it is important to remember what society was like when Milton wrote the poem. In particular, during that time period, there were certain "stock responses" to elements that Milton would have expected every reader to have. As examples, Lewis lists "love is sweet, death bitter, virtue lovely, and children or gardens delightful." According to Lewis, Milton would have expected readers not to view Satan as a hero at all. Lewis argues that readers far in the future romanticising Milton's intentions is not accurate.
Comparative religion scholar R. J. Zwi Werblowsky argues in his Lucifer and Prometheus that Milton's Satan is a disproportionately appealing character because of attributes he shares with the Greek Titan Prometheus. It has been called "most illuminating" for its historical and typological perspective on Milton's Satan as embodying both positive and negative values. The book has also been significant in pointing out the essential ambiguity of Prometheus and his dual Christ-like/Satanic nature as developed in the Christian tradition.
