Islam owns atheism with a single verse

[Loaded dice]

Right. That's why moral judgments shouldn't rely on anybody's perspective, including yours.

Or Mohammed's, or Allah's perspective either.  Just as subjective as my perspective.

I think you're having a hard time understanding what a hypothetical is.

Let me remind you of the context of this discussion : you're here claiming that hell, if exists, is immoral. Under the hypothetical of hell's existence, one presupposes that God exists and that some religious account of hell or similar eschatological worlds turned out to be true.

So, in this context, God's perspective isn't subjective, it's objective, as God is the absolute moral arbiter. If you want to play the "all religions are subjective" trump card, fine, but you can no longer object to hell. 

Take some time to grasp all that before writing any more stupid one-liners.

One criminal dying a natural death is infinitely more moral and just than torturing the criminal for eternity.  I find all hell-focused religions, and their deities, to be utterly abhorrent.

Again, presupposing that eternal punishment exists means that you should abide by the rules of the religious worldview. Your goal, as an atheist, should be to bring out a contradiction in this worldview if we accept all of it. 

You can't have it both ways : if you want to criticize the eschatology that is claimed by theistic systems, you should take into account all the elements of the theistic system, which usually include God being more acquainted with moral facts than you.

Another example to help you understand : if you want to win in chess, you need to accept all the rules of chess (and so should your opponent) and then play optimally, even if you think you would have a winning position if such and such rule is omitted. Back to our discussion : once you find yourself cornered and not able to bring out any logical problem in the concept of hell, you arbitrarily change the rules : God is no longer the objective moral lawgiver, God is subjective... that's not how it works. And needless to say that by doing so you're begging the question of your worldview being correct.

So, I hope I am not playing chess with a pigeon.
