Well, we definitely delve a bit into the realm of speculation on these issues, but I'm not so certain satan's fall happened in Heaven. Most of what we glean about "the shiny one" lucifer, we get from Isaiah 14 and Ezekiel 28. Notice how these verses seem to indicate his fall happened on Earth, in Eden.
“You were the seal of perfection,
Full of wisdom and perfect in beauty.
13 You were in Eden, the garden of God;
Every precious stone was your covering:
The sardius, topaz, and diamond,
Beryl, onyx, and jasper,
Sapphire, turquoise, and emerald with gold.
The workmanship of your timbrels and pipes
Was prepared for you on the day you were created.
14 “You were the anointed cherub who covers;
I established you;
You were on the holy mountain of God;
You walked back and forth in the midst of fiery stones.
15 You were perfect in your ways from the day you were created,
Till iniquity was found in you.
On the face of it this passage alludes to the possibility that satan was in the Garden of Eden when the original iniquity was found.
He absolutely wanted to be worshiped, and STILL does, as God,but I think he wanted other attributes of God as well, and certainly the ability to create matter, and especially sentient, organic matter, coupled with the desire to be worshiped, is what led to the birth of his iniquity.
God created beings, capable of love and worship.He wanted to be, or emulate, The Most High God. He and his followers could NEVER duplicate love, but in a warped, distorted way, his children worship him, and the rest.
Again, I don't want to make settled doctrine over this, just hashing it out brother.
