The only Scripture quoted in response to me that even attempts to answer what I've asked has been a passage in Matthew concerning the future judgment of the devils.
I didn't ignore, I asked if that passage was relevant.
I'm seeing a lot of assertions, but that's it.

That was not an assertion, the scripture you mentioned explained it. It speaks of the destiny of those devils in question, which in turn reveals their eternal motivations. If there was a chance they could turn around and say sorry from the position they are in now, don't you think God would have been a little less specific about their eventual destination?
You need to look at this question a different way...what evidence is there that the fallen angels WILL repent, rather than looking for evidence that they won't. There's no picture in the Bible that I can see of a change in the behavioural structure of Satan's kingdom. Satan and his devils are described as a "roaring lion" roaming around looking for people to destroy. Where in the Bible does it say that some of them take a chill pill and start working for God?
How about:
2 Peter 2
4 For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment; 5 and did not spare the ancient world, but saved Noah, one of eight people, a preacher of righteousness, bringing in the flood on the world of the ungodly;
or
Jude 1:6
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;
Let's face it. Angels rebelled against God right in front of His face. They made an eternal shift in their eternal spirit, right before God. They didn't have our excuses, or our earthly lives which can be redeemed through the blood of Jesus. They saw God face to face and went against Him.
Luke 12:48
But the one who does not know and does things deserving punishment will be beaten with few blows. From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked.
If you still don't think that's evidence, then I'm sorry but I can't help you. But i'd like you to show me some evidence that the Bible says fallen angels can turn around and go back to Heaven.
