Satan has no power to do anything unless he is given it by his Creator.
He cannot curse unless there is legal cause, and God gives him the legal right to curse.
the evil spirits in heaven are created to do what they do, and their rewards are the prey they get to believe their lies.
Therefore; the unworthy are separated from the Creator for eternity in the second death, and by their own deeds of believing the lies of the murderer who was and is the Prince of Darkness, they go to their own rewards and are tormented forever by the satans they made themselves subject to.
The myth that there is a fallen "cherub" named "lucifer is debunked by the Jews themselves, whose language does not give the word "light bearer" as a proper noun.
The myth of a fallen cherub named lucifer is not based upon the doctrine of the Living Oracles or of the prophets of God: from Enoch the prophet to the closing of the book of Revelation, there is no such doctrine anywhere. It is a lie formed by ignorant men whose ancestors cast out the wisdom given to Enoch to write for all his descendants.....of whom are all born in Adam since the flood -but not all cast it out; it is canon [man made rule] in the Ethiopian Orthodox Churh and was kept in the "bible" which word means "collection of books", of the sons of Zadok/the priesthood line who are written of in Ezekiel and who are called the "essenes" who left their manuscripts in the caves at Qumram, to be discovered in these last days.
Enoch wrote his book for those who will be living in the last days, when the great tribulation is upon the world, as the opening of it declares he did, and which opening Jude, womb brother of Jesus the Christ come in flesh, quoted from.
Enoch also wrote of the rapture of the saints before that great tribulation, in chapter 50, and of those who are saved by believing in the name of the Son of Man but who do not get the glory -they go through the tribulation, and some are martyred in it, but all are raised in the end of it as part [the gleanings of the harvest], of the first "resurrection to life" -and then there is no more resurrection "to life" ever, and the earth no more covers her slain, as Isaiah wrote in 26: 19-21, and all who die in the millennial reign die the second death as "accursed", and go straight to the LAke of Fire and do not stand for any more judgment at the end of it, for in that "Day" he Glory dwells among men [Ezekiel 44]; "tabernacling among men" to fulfill the last of the seven Oracles of Messiah's Person and work and "the earth no more covers her slain"...
The Dead Sea Scrolls corroborate the Word written in Enoch and the Torah and the prophets after, which teach of the unclean spirits in heaven who were created there to test, tempt, try the sons of men and the holy watcher angels.
After the flood, the descendants of the sons of Noah could not take the afflictions put upon them by the curse God gave the disembodied offspring of the fallen watchers and sought Noah to pray to God for their deliverance from them and to have them cast into Sheol....God listened to Noah and was going to throw them all there, but the "Prince of the Satans/Prince Mastema, reasoned with God that he could not do his work unless God left some for his use [weeding out the unworthy, who become his "food and drink in the Lake of Fire, to torment them forever]. God listened to that reasoning and left one thenth of them on earth until Messiah sets up His millennial reign. .. That is found in the record come down in the Book of Jubilees, which is also in the DSS and in the Ethiopian Orthodox Church. The Hebrew word "Mastema" means "satans".
The demons/evil spirits roam earth, seeking bodies to use to do their evil deeds and to afflict and torment, and have the legal authority from God to do so until they are gathered by the angels at the coming of the "Anointed Holy One of God/Christ/Messiah" to reign over His ransomed kingdom, which He will cleanse of all evil for the millennial Sabbath reign of it, by sending His angels to gather all the tares up and throw them into the fire -the Lake of Fire, where they will be tormented by satans there, forever, because they are the "bastard seed/darnel/tares" spirits from the fallen watchers who had illegal Adam flesh to dwell in, which was created by the unlawful union of fallen Watchers and daughters of Adam..their bodies will not rise, they are the dead/rapha -they will not rise, as Scripture states, but they seek bodies of human beings to control for evil.
The satans do not have bodies, they are evil spirits in heaven. The demons are evil spirits on earth and cannot enter heaven.
This is all in the Book of Enoch.
Enoch wrote all that before the flood, and it is for the generation who will be living in the great tribulation.

The two men of the Gaderenes [Gentiles, in fact] who were tormented by a legion of evil spirits/unclean spirits/demons, knew the time appointed was not come for their being thrown into the Lake of Fire for torment, there, forever, at the hand of the evil angels created in heaven called "satans". They knew this because Enoch delivered the Word of God to their fathers, the fallen watchers, telling the doom of their offspring and their doom.
Those demons who called themselves "legion" said to the Holy One of God/Messiah/Jesus Christ; "I know you, you holy One of God, are you come to torment us before the [appointed] time"?
Their appointed time to be tormented is when Jesus comes to set up His milolennial Sabbath reign, at the end of the second " great consummation of sin on earth" which Enoch wrote was to come, before even the flood which was the first "consummation of sin on earth" which Enoch wrote of, came.
