Well, I think the usual Christian position is that he created humanity without sin (so no need for hell). Then the fall happened which meant disobeying God. Like any loving parent there had to be consequences for not listening to (ie accepting Gods grace and following his rules) ie Hell- being outside Gods Grace. He bestowed Free Will on us (thanks Thomas Aquinas - good catch) so everyone has a chance to be saved.
The Bible, of course is a lot more complicated as it developed over time..
Hell didn’t really exist for the Old Testament - you have Sheol/hades which is a neutral place for the dead. The Book of Jonah (basically where a lot of the Gospel story was copied from - Jesus even cheekily acknowledged that - has Jonah praying for salvation from Sheol where he spent 3 days after sacrificing himself (body in the whale- soul in Sheol). Interestingly here the people of the capital of Assyria were saved because they repented, God acknowledged there was no need to believe in him. This reflects the idea that Jews were held to a higher standard but were not the only people who could be saved. God had a mission for Jonah - he ignored the Will of God and was punished for it. The NT is a sliding doors moment for the Book of Jonah in many respects. The New Testament never says that Jesus went to Hell in those 3 days - he went deep into the Earth - it’s the Apostles Creed that does that properly.
We shouldn’t forget Jesus was largely preaching to Jews.
The mention of Tartarus in 2Peter2:24 refers to Angels being thrown by God into the darkness.
Theres a few mentions here and there of places that could be read as hell - but nothing you could really hang your hat on.
According to Revelations- people will only be cast into the lake of fire at the day of Judgement- This eschatological hell enhanced by poets and painters is what people mainly think of - but then Revelation states 144,000 will be saved- 12,000 for each of the 12 tribes of Israel - suddenly no one wants a literal reading of the Bible at this point and there a lot of tying in knots over this. Conveniently, the New Jerusalem is 12000 stadia wide, long and high which should make it pretty easy to carve up between the tribes of Israel - each tribe has even got its own Gem stone. Chances are Christians won’t be getting a ride on this space ship. Jews were always Gods chosen people after all. Never mind, the Devil always had the best tunes and heaven without decent music is no heaven at all - there’s bits though in the NT saying all Christian souls are in heaven though (I think this is where predestination comes from)
Theres lots of other versions, Earth being hell - created by the demiurge God of the Old Testament (Gnostics) Emanation and reflection - Neoplatonic and all the usually mystical believers who followed (no hell just far away from the light), pain being necessary for God to experience all aspects of itself (the purpose of creation-etc etc.
So Hell is largely man made
