WHAT? IF there is a God and if he doesn't let you get your way then you think he's not much of a god? Goodness man, there's more than a little bit of arrogance in there! Look around you, the evidence of God is observable. Faith isn't stupid. Faith is only blind if the seeker refuses to see and no one can "see" with his eyes squeezed shut. And blind professions of belief without trust is meaningless
Truth is, "faith" isn't magic and it certainly isn't blind. Faith simply means "trust", meaning we see His hands at work and have faith (trust) that he will continue to do the same. As we mature our faith grows progressively stronger as we see more and more of his trust worthyness. So, IF there is such a God, it should be obvious that He has every right to "judge" you and everyone else as he sees fit.
I think you are looking through the wrong end of life's telescope. It's a mistake to see God as someone who is - maybe? - a slightly bigger human who really ought to give your ideas a fair consideration when making his plans. But nothing you think is unique in history and God hasn't yet asked any man what he should do about anything.
You're badly misunderstood the two most critical things about God's coming judgements.
First and foremost, his coming "judgement" won't about heaven or hell for us, we each make that choice for ourselves (John 3:16-17).
God is no tyrant. Suggesting he may be "unfair" to you is foolish. You have the same basic information as the rest of us and God gives you total freedom to live as you wish. He simply lays it all before you and lets you make your own choice about who is right and who is wrong.
Quit majoring on minors, quit agonizing over accounts of the days of creation, the flood, feeding with fishes, etc., and focus on Jesus himself. IF you choose to reject him and his agonizing blood bought and freely offered gift of eternity in God's heaven you have, by a binary default, chosen to live eternally separated from Him. And that ain't cool!
You know the rules, you've been warned. You can't rightly say God has done you wrong when he simply lets you live with the results of your own decisions.
Second,
about rewards or punishments in the after life; what God WILL judge you for is how you have lived. Your level of eternal punishment will be determined by how bad you've been and how far reaching the effects of your harm goes; you will get the punishment you've earned, nothing more or less. And, for what it's worth, the saved, i.e., those who have trusted to follow Christ, will participate in making the Great White Throne judgement of your after life.
None of this is a secret, it's all in the Book.
