I agree.
And I would not be surprised and believe that the fallen angels had some kind of opportunity at salvation. And it was rejected.
That rejection of salvation of the fallen angels was the reason for Satan's wager over Job. (will explain if asked).
Jesus had no need to die for the fallen angels.
For, though they had fallen?
Unlike fallen man, they remained spiritually alive and could receive from God His message for repentance.
Man is soul.
Soul, though immaterial, is not spiritual.
That is why we need to be given a human spirit to know the things of God.
As for angels? They are spirit beings. Not souls like men.
They remain even now capable of comprehending the things of God.
For, the evil spirits that Jesus confronted instantly knew He was the Son of God.
That is when Jesus commanded them to be silent.
One example of what I speak.
Just then a man in their synagogue who was possessed
by an impure spirit cried out, “What do you want with us,
Jesus of Nazareth? Have you come to destroy us?
I know who you are—the Holy One of God!” (Mark 1:23-24)
The Pharisees with souls could not tell who Jesus was. But? Fallen angels instantly knew!
So, God only required repentance from Satan and his angels to be reconciled. But, Job covers
an unspoken aspect of what happened when God was wishing for the fallen angels to repent.
