I’ve wondered what happens if a demon want to repent. Lucifer mislead 1/3 of angels. Some of them have got to have woken up and realized they were played for fools.
Unlike humans, Angels have infused knowledge and perfect control of their will. Therefore once the fallen Angel’s made a choice against the will of God, there is no chance of repentance.
I’m sure a lot of human souls in Hell also wish they had a second chance.
Problem is they had their full lifetimes to do so and they didn’t.
Their choice.
Christ Jesus did not die for them, only man, so they are done for.
