I don't actually believe in a literal Satan, but he is a symbol for both the Romantic and the Rationalist. The Revolt of the Angels by Anatole France expresses what I mean. It's public domain and can be easily read online free legally.
Its reasonable whether literal or a symbol, #7 contradicts the concept of "romantic rationalism".
I already know everything I need to know about the revolt of the angels, from the Bible--the only 100% correct source of information. None of them rebelled against authority, they rejected holiness desiring instead what is improper:
1 Now it came to pass, when men began to multiply on the face of the earth, and daughters were born to them,
2 that the sons of God saw the daughters of men, that they were beautiful; and they took wives for themselves of all whom they chose. (Gen. 6:1-2 NKJ)
While this text is about angels who didn't join Satan's rebellion, they still wanted sexual relations with humans as did the Nephilim "Fallen Ones":
The fallen ones were in the earth in those days, and even afterwards when sons of God come in unto daughters of men, and they have borne to them -- they are the heroes, who, from of old, are the men of name. (Gen. 6:4 YLT)
Without Holiness its impossible to be in God's presence. All enslaved to perversion and sin will be outside of God's Holy Presence. In effect, God gives them what they chose, they exist apart all that is good and fun to enjoy:
14 Blessed are those who do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city.
15 But outside are dogs and sorcerers and sexually immoral and murderers and idolaters, and whoever loves and practices a lie.
(Rev. 22:14-15 NKJ)
You should repent and believe in Jesus Christ for your salvation, before the door that is open, shuts:
24 "Strive to enter through the narrow gate, for many, I say to you, will seek to enter and will not be able.
25 "When once the Master of the house has risen up and shut the door, and you begin to stand outside and knock at the door, saying,`Lord, Lord, open for us,' and He will answer and say to you,`I do not know you, where you are from,'
26 "then you will begin to say,`We ate and drank in Your presence, and You taught in our streets.'
27 "But He will say,`I tell you I do not know you, where you are from. Depart from Me, all you workers of iniquity.'
28 "There will be weeping and gnashing of teeth, when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and yourselves thrust out. (Lk. 13:24-28 NKJ)
