I wouldn’t go so far as to say we’re commanded to love them, Dan. For one thing, we have absolutely no clear experience of them, not even so much as we might have of a tiger, so how could we love them (imo)? Whether or not Father loves them is another matter and I don’t feel confident to say that He does not.
Logically, if they exist as personal beings (as opposed to personifications of evil – anthropomorphisms), then it seems that as conscious creatures, creations of God, though they may become monsters – yet they would be the first candidates (and the only ones I can think of) for “those of the heavens” spoken of in Colossians.
Nevertheless, they aren’t our responsibility – not like our brother and sister humans. Scripture isn’t all together clear as to their fate. Still, there’s the story how Father used Job’s guileless and true nature as an example to the devil. Whether parable or history, there it is. Aside from not blaming our brothers and sisters for their own misfortunes, and giving us a hint of an understanding of the glory and magnificence of God, what else does that story teach us?
I do believe that if they exist as personal beings, fallen angels/demons/etc. must either be reconciled or annihilated since God will be all in all, and all things will be summed up in Christ. The all summed up on Christ cannot include evil, so it cannot include unreconciled fallen angels even if they’re in torment. But as death is destroyed – the last enemy cannot be the FIRST death, either – annihilation doesn’t look like a possibility. It makes sense to me that at some point they too will repent. Maybe Jesus’ sufferings were for us and OUR sufferings are for the fallen angels – to cause them to see their sin in the suffering of the human race and repent? (SHEER speculation, but it’s a thought.)
