In the Bible, it has no evidences that fallen angel is Satan. The fallen angel theory was originated from not the Bible but just the guessing of human being. Absolutely, any words not supported by the Bible cannot become the truth. To rightly know the true nature of Satan is indispensable to help God and Jesus defeat Satan.
According to the Bible, Jesus said. “Satan the devil was a murderer from the beginning, and abode not in the truth, because there is no truth in him” (John 8:44). If Satan is a fallen angel, Jesus couldn’t define him as “a murderer from the beginning, and abode not in the truth”.
Furthermore, Satan, a great red dragon drew the third part of the stars of heaven, and cast them to the earth (Rev. 12:3~4):
3. And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.
4. And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.
Indeed, in the last war, Satan is so powerful to cast the third part of the stars(angels) of heaven. In reality, Satan seduced angel to be fallen from the heaven. This is the Very Secret of Secrets. Now, the fallen angels are in everlasting chains under darkness unto the judgment of the great day (Jude 1:6):
6. And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.
So, the active bad ones are not fallen angels but devils of Satan. To rightly help God and Jesus, first and foremost, all Christians have to know that God and Satan have been fighting against from the beginning.
The man was created as soldiers to defeat Satan.
