"At one time the Watchtower actually correctly identified Abaddon as Satan."
Abaddon... is not Satan... and he certainly is not the Christ. How do we know he is not Satan? Abaddon/Apollyon... is The Destroyer... whom my Father unleashed upon Egypt, upon Israel, and upon the Assyrians. JAH would never unleash Satan upon His people Israel to kill them. He allows temptation and persecution, yes. But death by the hand of Satan, no. Abaddon is bound NOW; Satan, is to be bound later.
Hebrews 11:28; Numbers 11:33; 1 Corinthians 10:10; 2 Kings 19:35; Revelation 20:1; 9:1, 11; Job 1:12; 2:6; 26:6
Satan... is to be bound in Abaddon's realm... the abyss... for 1,000 years... but that has not occurred... yet. Up until THIS time, he was:
1. One of the angels of the ark, or arkangel... or "cherub that is covering" - Ezekiel 28:14; Exodus 25:18
2. Assigned to Eden... or "Persia", the land where Eden was established - Ezekiel 28:13; Daniel 10:13
3. After his act in Eden, he still was able to "go in and out", like all spirit beings except those who are "bound" in Tartarus - Job 1:6, 7; Genesis 28:12
3. Cast out of Eden, the garden of Paradise ("heaven")... by the OTHER angel of the Ark, Michael - there were only two, and they were EQUAL; the thing GREATER than THEM... was the COVER, or "Propitiatory", my Lord, who is the Truth and toward whom they were BOTH supposed to keep their faces (i.e., remain in union with; "stand fast IN") - but from whom Satan turned his, trying to make himself not only higher than my Lord, but higher than God - so that eventually he was cast down to the earth by Michael, when my Lord was established as king - Exodus 25:18-20; Jude 9; 1 John 2:2; Ezekiel 28:17; Psalm 147:6; Isaiah 14:12-15; Revelation 12:9-12; Matthew 28:17; Daniel 10:13, 21; Jude 9; John 8:44; John 14:6
In the future, he will be:
1. Bound for 1,000 years in the pit of the abyss, over which "rules" Abaddon, the king of the abyss - Revelation 20:1
2. Set loose from that pit for a short time, during which time, there is NO death, but only destruction by fire from God, because for any to die, they would have to be resurrected, either to life or to judgment, but those who die then, die by means of fire directly from God, and thus are simply destroyed... body AND spirit... including Satan. Death, is held at abeyance during this time; only Satan is released from the abyss. Death, the LAST enemy... is hurled into the Lake of Fire later, and afterward "in no more" - Revelation 20:7-10. 13, 14; Matthew 13:25, 39; 1 Corinthians 15:25, 26; Isaiah 25:8; Hosea 13:14
May you have eyes to see... and ears... to hear. I bid you peace.
A slave of Christ,
