I agree with parts of this, however to compare satan to human beings is really the epitome of apples and oranges.
satan did not have satan to tempt him. Humans did. I think God recognizes this fact, and that is why He became a HUMAN, not a an angel, or nephilim, to die for OUR iniquity.
So now that I'm getting a little controversial, I'm going to throw out the possibility that satan may have been tempted BY humans. How? Why?
Most people believe satan was jealous of Adam's creation and election to rule over the world. While I think that's true, I'm going to submit there may be a far greater temptation, that he, and his followers miserably failed at, and is why they are reserved in judgement.
As an Angel you have unbelievable power, access to the Heavenly Father, eternal life in joy and bliss, but ONE thing you DO NOT have as an Angel is the ability IN HEAVEN to procreate! ( Yes I went there lol).
The temptation to leave their "Heavenly estate" and Procreate with human women, was too great. Notice how Jude couples the SEXUAL SIN of Sodom, to the SEXUAL SIN of the fallen Angels:
6 And the angels who did not keep their proper domain, but left their own abode, He has reserved in everlasting chains under darkness for the judgment of the great day; 7 as Sodom and Gomorrah, and the cities around them IN A SIMILAR MANNER TO THESE, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.
But I absolutely agree with you that the self-same lie, that you can be like god, is what tempts people away from Salvation through Jesus Christ.
I know there are quite the few here that highly offended with even the suggestion that fallen Angels mated with human women.
I'd say to them, it's not a Salvation issue, and I love you.
