Just out of curiosity, who will make those who worship the demon Christian god pay? Is there some other all-power sky king we don't know about who you believe has the power to punish them? Sounds very similar to Christianity: worship as I say or pay the price.
I see no more proof for your version of how life and existence works than I do for what the Christians believe.
No one punishes them or makes them pay; they do it to themselves. This is a natural law, just like gravity or the fine structure constant; when you leave the material body there are no more delusions.
If you are genuinely seeking an honest response, then I will give it a shot.
We've been taught in some capacity or another that Adam and Eve were kicked out of the Garden of Eden because they made a mistake and sinned. This has lead many to grow up thinking that their value and their worthiness of being loved and/or saved is based on how well they perform. That couldn't be further from the truth. The reality, and you can go to Genesis 3 and read for yourself, is that Adam and Eve were kicked out of the garden because they didn't take ownership of their sins. Eve blamed the serpent. Adam blamed Eve. God looked at them both and was like, "I know where this is going..." So when we repent of our sins, it's not bowing down like a slave and declaring that God is your master. God doesn't want slaves, and he doesn't want us living with a slave mindset. In fact, God wants us to live like royalty. Repentance is a choice. It's saying, "I'm going to take ownership of myself align myself with not only who God is, but who He created me to be." That's when relationship with God is established, and since God is a good and loving God who wants us to be the absolute very best that we were created for, it makes for a pretty wild and amazing ride.
So going back to your original question of why Hitler would go to heaven and the school teacher would go to hell, we need to look at it from a different angle. Leave the performance side out of it. In your scenario, Hitler lived his life and turned back to God near his end. The school teacher rejected God their whole life, and may have not. If we live our whole lives thinking that our actions could never possibly be forgiven, then we don't know God. And additionally, if we live our whole lives thinking we're unworthy of being loved, then we're believing a lie.
You are worthy. You are loved. You are made good. You are made for great things.
This is gaslighting, emotionally-lead bullshit from start to finish.
First of all, the fruit Adam and Eve ate was...wait for it...from the Tree of what now? That's right,
Knowledge of Good and Evil. Which means before they ate it, they couldn't...waaaaait for iiiiiit....know it was wrong to eat it.
Furthermore, your God is supposedly omniscient and absolutely-sovereign. This means he knew exactly what would happen when he put the fruit
smack in the middle of the garden, and then decided to put a snake...a talking, four-legged snake...whom he know would tempt his creation...in the tree.
And then he absolutely
pissed himself when he realized his creations ate the fruit, throwing a decidedly non-monotheistic hissy fit and saying "Behold, man has become as
one of us, knowing good from evil."
What the hell was he scared of anyway? And who's "us?" Don't bullshit me and tell me "Elohim" was being used as the "majestic singular-plural;" that was El, who at this point had
not been syncretized with Yahweh yet, cacking his cassock over the idea that his creations weren't just weird little flesh robots anymore.
Which of course goes against divine omniscience but fuck that, it's not like the core attributes of what it means to
be God are important to any discussion of God, riiiiiiight?
And what "wild and amazing ride" are you talking about? There are only two destinies for humans according to your religion: spend eternity kissing El-Yahweh's ineffable ass in a heaven that, as per Revelation, looks like a cross between Trump Tower and the Borg Cube, or spend eternity--
forever!--in literally unimaginable torture for
not kissing said ass before death.
I say this with no irony whatsoever: Go to Hell. Go to that Hell you love so much. It's your Hell,
you go there, and take your narcissistic, genocidal Bronze Age throwback with you. If any being could possibly even be barely imagined to deserve eternal torment, it's this demon you worship as a God.
