> The point of our(mostly doomed) existence?
Already I'm sensing some inner suffering over this along with confusion about it. I'll start off by saying I'm sorry you feel so burdened and angry. I'll try to answer your questions and we can talk.
> (forced as in not having a choice being born/being here)
To me it seems weird that you seem to think that beings who don't exist should get to have a say in whether to come into existence or not. I just don't get where that's even possible. But you're upset that you, before you existed, didn't get input into your own existence. But we'll keep going here.
> What is the point of our compulsory, forced existence
At least some of the point of life is to experience love, friends, beauty, fun, truth, learning, adventure, and a whole bunch of other stuff. Despite the agonies of life, there is a lot of positive, also.
> ...will ultimately have us be thrown in hell to be tormented savagely forever?
It's God's desire that you join His family and experience forgiveness, healing, love, wholeness, freedom, and truth. That's what He invites all people into a relationship with Him for. The Bible specifically says that hell was designed for Satan and his angels, not for humans at all. But if you reject God, then the only alternative to being with God is being separated from Him. And, by the way, hell isn't savage torment, which makes it sound like God is getting some kind of perverse delight out of it. It's punishment that appropriate to the offense, which I think everyone would agree is a principle of justice that we all affirm.
> More precisely, if we're born to just to die physically and spiritually
It's more accurate to say that we're born so that we can come into relationship with God. But if you don't choose to do that, then that's not God's fault. You have plenty of opportunities to come to Him, and this conversation is even one of them.
> I understand that there was a way made out of this inevitable and inescapable fate through Christ
C.S. Lewis wrote (and I think he makes a valid point):
You object to the doctrine of hell. What are you asking God to do? To wipe out past sins at all costs and to give anyone who wants it a fresh start, smoothing difficulties and offering help? But He has DONE that. That's what his death and resurrection were all about. OK, then, are you asking God to forgive you? It's a RELATIONSHIP. He will forgive anyone who wants it, and cannot forgive those who choose not to be forgiven. To leave you alone then? Well, I'm afraid that's what hell is.
If a game is played, it must be possible to lose it. If there is a way that must be found by the will, and by love, then it must be possible to refuse it. If the happiness of a person is honestly the result of self-surrender, then no one can make that decision except himself, and he may refuse. I would love to say everyone will be saved. But then I'd have to ask, "Will they be saved against their will, or with it?" If I say "against their will," I'm in the middle of a contradiction; how can self-surrender and love be involuntary? But if the answer is "With their will," it begs the question: "What if they will not give in?"
> but in my view I feel like the representative majority of our existence is a very long cruel & joke.
Life without Christ can certainly feel like that, based on the testimonies of millions of people.
> We have no say whatsoever whether or not we will take up the multi-generational burden and satanic curse of sin & it's possessive dominion over our lives, consciousness & souls.
That's exactly the point: We DO have a say. At any time that can be taken away. Forgiven and removed. It's like parents who would renounce their American citizenship and move to, say, France. So their children, through no fault of their own, are not Americans but French citizens. But it's true (for the sake of this hypothetical analogy) that any time any of those children can choose to move back to the US and become American citizens, if that's what they want to do. Their parents' decision doesn't rule their lives.
So also, Adam & Eve's decision transferred your "citizenship" away from God, and you were born separated from Him. But the door is always open: You can come back ANY TIME you want. Adam & Eve's decision doesn't rule your life; YOU rule your life.
> So I come to you to ask: what's the point of being here if you can't live your own life on your own terms without there being some kind of eternally violent and unimaginably terrorizing fate at the end of it?
Because everything has consequences. It's impossible that there not be any consequences. There are consequences in science, in knowledge, in learning, in communication, and in relationships. There's no other choice. If you want to live life on your own terms, go ahead, but there are consequences. We live in a real world where we don't just make up consequences willy-nilly. We live in reality. And IF there's a God, then there are truly consequences for both accepting or rejecting that truth. Otherwise all of life is just an illusion, and a meaningless one at that—but that's not reality.
