Question 1: Why does Milton hate Eve so much?
Milton definitely portrays Eve as the weaker sex. She’s less intelligent and can’t communicate directly with God. However, that’s completely contrary to the actual Bible. Sure, men were mostly chosen by God to be prophets, and kings. But women, while fewer in number as holders of power, were arguably far more important than men. Mary is more revered than Joseph, for example. I think that Milton definitely put a lot of his own opinions into Paradise Lost, and that’s why it’s important to consider the fact that Paradise Lost is basically a fan fiction retelling of its source material. God didn’t hate Eve for disobeying, but Milton definitely portrays it that way, putting the entire blame on Eve for being a silly woman rather than how both Adam and Eve were at fault:
O Eve, in evil hour thou didst give eare
To that false Worm, of whomsoever taught
To counterfet Mans voice, true in our Fall,
False in our promis’d Rising
Question 2: How does Satan change throughout the narrative?
In Book 1, Satan was a sympathetic character, which was probably a controversial take on the Bible in his time. Satan’s intentions are completely understandable at first – Satan wants to be independent and not have to follow God’s rule over the angels. Throughout, he’s portrayed as a military leader who sometimes doubts his intentions. But in Book 9, Satan completely commits to his evil purpose and causes the fall of Adam and Eve. It’s a really interesting character arc, where Satan starts out as a three dimensional, sympathetic villain, and then devolves steadily into a completely evil force.
