The ultimate antidote for demonic doctrine, and even THE final authority to determine exactly what demonic doctrine consists of, is The HOLY BIBLE and proof-text references therein.

To being with, God the Creator did not create us because He was lonely or inadequately had a need to have human companionship. Rather, it is simply His nature to create scentient beings besides the Four Living Creatures, 24 Elders, cherubim and seraphim, etc.

Moreover, however we humans as individuals use our free wills to decide whether to be for or against God, God Himself does not suffer. We cannot make Him sad nor cry and bawl if we decide to reject His love and disobey Him. He, in that sense, couldn't care less what we decide and do. When Scripture tells us to "not grieve the Spirit" (Ephesians 4:30), that "grieving" is not us having power over God by forcing Him to become unhappy, but is rather an retribution-causing intention and action of the Spirit for which we will become very unhappy because of the consequences of not complying with the will and word of the Lord. Indeed, even "enraging" the Spirit of grace, thus making God "angry," is not us sadistically discomforting nor disillusioning Him, although He sure can do that to us! Job 35:6 reminds us, "If you have sinned, what do you accomplish against Him? And if your transgressions are multiplied, what do you do to Him"? NO one, be they an errant human or demon, can harm the Lord.

Is there pre-knowledge and pre-destination? Does God know what the future will be before it happens? Does He know whether or not humans yet not born nor even conceived will end up in Heaven or instead in Hell?

Acts 4:28 = .....to do whatever Thy hand and Thy plan had predestined to take place.

Romans 9:13-23 = As it is written, "Jacob I loved, but Esau I hated."
14 What shall we say then? Is there injustice on God's part? By no means!
15 For he says to Moses, "I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion."
16 So it depends not upon man's will or exertion, but upon God's mercy.
17 For the scripture says to Pharaoh, "I have raised you up for the very purpose of showing my power in you, so that my name may be proclaimed in all the earth."
18 So then he has mercy upon whomever he wills, and he hardens the heart of whomever he wills.
19 You will say to me then, "Why does he still find fault? For who can resist his will?"
20 But who are you, a man, to answer back to God? Will what is molded say to its molder, "Why have you made me thus?"
21 Has the potter no right over the clay, to make out of the same lump one vessel for beauty and another for menial use?
22 What if God, desiring to show his wrath and to make known his power, has endured with much patience the vessels of wrath made for destruction,
23 in order to make known the riches of his glory for the vessels of mercy, which he has prepared beforehand for glory.....

Romans 8:29 = For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the first-born among many brethren.

Romans 11:2 = God has not rejected his people whom he foreknew. Do you not know what the scripture says of Elijah, how he pleads with God against Israel?

I Peter 1:1-2 = Peter, an apostle of Jesus Christ, To the exiles of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia, chosen and destined by God the Father and sanctified by the Spirit for obedience to Jesus Christ and for sprinkling with his blood: May grace and peace be multiplied to you.

Consider also these verses:

Ephesians 1:5 = He destined us in love to be his sons through Jesus Christ, according to the purpose of his will,
Ephesians 1:12 = we who first hoped in Christ have been destined and appointed to live for the praise of his glory.
I Thessalonians 5:9 = For God has not destined us for wrath, but to obtain salvation through our Lord Jesus Christ,
I Peter 1:2 = chosen and destined by God the Father and sanctified by the Spirit for obedience to Jesus Christ and for sprinkling with his blood: May grace and peace be multiplied to you.
I Peter 1:20 = He was destined before the foundation of the world but was made manifest at the end of the times for your sake.
I Peter 2:8 = and "A stone that will make men stumble, a rock that will make them fall"; for they stumble because they disobey the word, as they were destined to do.

The above verses more or less speak for themselves, and they speak powerfully! Though God knows what will happen before it happens, before it 'comes to pass,' and even creates and causes the conditions and environment within which it will happen, He gets the credit for a few humans using their free wills to comply with and accomodate to Him, but is not responsible nor to blame for many humans (on the broad and easy road to destruction) using their free wills to rebel, reject, misrepresent, and disobey Him.

The many who do go awry are of course destined for hell.

On that subject, we have to study what Scripture has to say about hell, and one presumption we never find in the Bible is that hell is God the Father and Spirit suffering by Christ dying on a cross. The punishment due for our sins might be mis-described as our "hell" to and for Christ on His cross, but actual hell is something else entirely.

In Luke chapter 16, we find not this tale nor this fable, nor even this story, but instead this historical account from the mouth of Jesus:

19 "There was a certain rich man, who was clothed in purple and fine linen and fared sumptuously every day.
20 And there was a certain beggar named Lazarus, who was laid at his gate, full of sores
21 and desiring to be fed with the crumbs which fell from the rich man's table. Moreover the dogs came and licked his sores.
22 And it came to pass that the beggar died, and was carried by the angels into Abraham's bosom. The rich man also died, and was buried.
23 And in hell, being in torment, he lifted up his eyes and saw Abraham afar off and Lazarus in his bosom.
24 And he cried and said, `Father Abraham, have mercy on me, and send Lazarus that he may dip the tip of his finger in water and cool my tongue; for I am tormented in this flame.'
25 But Abraham said, `Son, remember that thou in thy lifetime received thy good things, and likewise Lazarus evil things; but now he is comforted and thou art tormented.
26 And beside all this, between us and you there is a great gulf fixed, so that they who would pass from here to you cannot; neither can they pass to us, that would come from there.'"

In the Old Testament, there occurs the word Sheol to describe the state in which the dead find themselves. Such does not include the never-never-land fabrication of becoming rid of sins in some presumed "purgatory" to purportedly enable the then-self-righteously-made saintly dead to enter heaven.

Sheol (also known as "The Pit") was simply a word for the abode of the dead, both righteous and wicked, without elaboration as to the conditions experienced by either one. However, as you can see not only by the narrative of Jesus involving the rich man and Lazarus, but also by Christ's words in Luke 23:43 from the cross ['Today you shall be with Me in Paradise'], Sheol is comprised of both Hades and Paradise, and the conditions of humans therein is vastly different depending upon which one they are confined to. It is interesting to notice the sight of Abraham and the communication with Abraham which the damned rich man has while in Hades. If the outer-darkness (Matthew 8:12, 22:13, 25:30) within which there was "weeping and gnashing of teeth" had even THAT much sensual stimuli, Hell would not be so bad.

[To find the "weeping and gnashing of teeth" phrase, reference to a KJV-type Bible must be made:

Matthew 8:12 = But the children of the Kingdom shall be cast out into outer darkness. There shall be weeping and gnashing of teeth."
Matthew 13:42 = and shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth.
Matthew 13:50 = and shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth."
Matthew 22:13 = Then said the king to the servants, `Bind him hand and foot and take him away, and cast him into outer darkness; there shall be weeping and gnashing of teeth.'
Matthew 24:51 = and shall cut him asunder and appoint him his portion with the hypocrites. There shall be weeping and gnashing of teeth.
Matthew 25:30 And cast ye the unprofitable servant into outer darkness. There shall be weeping and gnashing of teeth.'
Luke 13:28 There shall be weeping and gnashing of teeth when ye shall see Abraham and Isaac and Jacob and all the prophets in the Kingdom of God, and you yourselves thrust out].

The "outer darkness" referred to might to some extent be compared to the frightening helplessness of being down in a cave when the tour-group leader turns off the lights, disabling everyone from even seeing their hand or anything else in front of them.

But, it gets worse.

The weeping and gnashing will not be heard by anyone confined within ultimate Hell except onesself. There will not be a chorus of wailers weeping in everyone else's audible range within the Outer Darkness. Instead, the crying and gnashing to occur will be by each individual in absolute solitary confinement......forever.

And the fiery torment?

We further read this:

Revelation 19:20 = And the beast was taken, and with him the false prophet who wrought miracles in his presence, by which he deceived them that had received the mark of the beast, and them that worshiped his image. These both were cast alive into a lake of fire, burning with brimstone.
Revelation 20:10 = And the devil who had deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are; and they shall be tormented day and night for ever and ever.
Revelation 20:14 = And death and hell were cast into the lake of fire. This is the second death.
Revelation 20:15 = And whosoever was not found written in the Book of Life was cast into the lake of fire.

The above passages remind me of "the burning bush" in the desert that fascinated Moses (Exodus 3:2-4, Mark 12:26, Luke 20:37, Acts 7:30,35)....which bush, though being consumed and being burned away, was constantly being renewed and revitalized to continue to be consumed and burned away. That reminds me of the verse in II Thessalonians 1:9 where evil humans, not simply their evil works, suffer the punishment of "eternal destruction" (RSV) or "everlasting destruction" (KJ21). In other words, accursed humans will never be annihilated into non-existence, but instead experience the fully-punishing non-relenting wrathful fury of eternally-continuing torment in the outer-darkness flames of the Lake of Fire. Sort of like being continuously doused with gasoline and set ablaze over and over and over again with none to rescue.
