I'm not a christian, but I grew up in a Baptist household, so I have at least a passing understanding of the Bible. Lemme know if I got any wrong.
If I'm understanding the bible correctly;
God Created heaven and Earth, Including Mankind and Angels
God is all-knowing and all-powerful
Relevant to this discussion, God created Lucifer and all the angels who sided with him.
God made Man in His image, and ordered the angels to serve them.
Lucifer, prideful of his own beauty, and envious of God's (at least perceived) favoritism of Man, and of God's position, started a rebellion in heaven and was/will be cast down into the lake of fire(aka Hell).
lucifer later tempted/took the form of the Serpent in the Garden of Eden and tempted Eve to eat of the Tree of Knowledge.
my conclusion: God, with full knowledge of what lucifer would do/become created him and set him on the path that led to his downfall, and to the Sin of Mankind.
Or to put it more simply; God created Sin through his foreknowledge of what Lucifer would become.
I'm not trying to start a shitstorm here, but this is the logical conclusion that I find myself at.
Any Christian pedes wanna poke holes in this for me?
First, you tell me if creating beings with no freewill is worth creating in the first place.
To quote the great C.S. Lewis:
Or, it is possible that, because God knows all that will happen, and can manipulate His creation, He may have plans that we cannot imagine for the fallen beings. For instance, I was recently listening to an Orthodox priest who mentioned a doctrine unfamiliar to me, that until Christ returns, there is a Hades for the condemned souls and they can be redeemed even from there. But at the end of the age, Hades will truly become Hell and there will be no escape. Demons appear to be irredeemable.
Before Christ's sacrifice, there was an afterlife of sorts that had two sections, one for the lost and one for the OT believers. The former doesn't really have a name, but the latter is called Abraham's Bosom, and the realm as a whole is called Sheol in the OT. This concept got conflated with Greek notions of Hades and Tartarus. Given the story of Lazarus and the Rich Man, Tartarus is an apt comparison to the place where the lost are tormented.
After Christ's death, He took the souls that were in Abraham's Bosom into heaven proper. The lost are left behind in what we now call hell. After the Millennium, these souls will be called up to the great white throne for judgment. Since they didn't trust Christ, they and hell itself will be cast into the lake of fire for eternity.
I'm sorry, but there's no room in scripture for the lost to be saved after physical death. It's common for Christians to concoct schemes whereby the lost get a second chance, or that they all get saved in the end (universal salvation). They mean well, as no one wants anyone to be in fiery torment for eternity. But the Bible indicates that this life is the only life you have to make the right choice.
