God created everything good.
Including sinless Angels - some of whom fell and were then called demons
========================
Demons are angels who fell:
"Satan
and HIS angels" = "the dragon
and HIS angels"
2 Peter 3
4 For if God did not spare
angels when they sinned, but cast them into Tartarus and committed them to pits of darkness, held for judgment; 5 and did not spare the ancient world, but protected Noah, a preacher of righteousness, with seven others, when He brought a flood upon the world of the ungodly
Rev 12
3 Then another sign appeared in heaven: and behold, a great red dragon having seven heads and ten horns, and on his heads
were seven crowns. 4 And his tail *swept away
a third of the stars of heaven
It is then a case of "Satan and HIS angels" vs the angels of heaven in Rev 12.
7 And there was war in heaven, Michael and his angels waging war with the dragon.
The dragon and his angels waged war, 8 and they did not prevail, and there was no longer a place found for them in heaven. 9 And the great dragon was thrown down, the serpent of old
who is called the devil and Satan, who deceives the whole world; he was thrown down to the earth,
and his angels were thrown down with him.
Matthew 25:41: “Then He will say to those on His left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the
devil and his angels.’”
Matt 12:23 “This man casts out demons only by
Beelzebul the ruler of the demons.”
