I will make it more clear:
Like I said, perhaps to you no person on Earth can ever deserves to be thrown in Hell.
But I think if you were to ask around in society, even Atheists will tell you, that although they do not believe in Hell, they too think that some nasty people need to burn in the Fire.
I have asked my Atheist friends at the University about the concept of Hell.
They denied existence of Hell.
However, when pressed, they most of them admitted that Hell would indeed be a fitting end for certain few individuals who had carried out unimaginable crimes.
Obviously, you dont agree with them.
Thats your choice.
Therefore, you calling it "unfair" does not make it unfair.
You are not the only judge.
The Supreme Court has 9 Honourable Judges.
That was no sarcasm. This is a serious debate, so far.
What so and so says or doesn't say is not evidence.
The evidence that it is unjust and cruel are very clear. It is not simply my opinion, but the conclusion of reason, logic, and justice.
First of all Justice:
It is not justice to punish someone for something that is not their fault, namely not believing.
Belief is subjective. There is no undeniable evidence of God and there is no undeniable evidence Islam is true.
Therefore an unbeliever cannot be blamed for not believing.
Secondly Excessive punishment. An infinite torture for a finite "crime" is excessive.
Even if they were rapists, mass murderers etc... it is bad enough, but infinite torture for not believing in something that is not undeniable - is even worse!
You will not find any Supreme Court Judges ruling that even the worst rapist be tortured for the rest of his life. (Not even some despotic dictatorship).
Yet God does that - and far worse! He does not just let them die - or punish them until they die. He keeps them alive forever! So they can be tortured in agnoy for ever.
Hell is both unjust and excessive.
If you wish to disprove that, you need to bring a proper argument - not what so-and-so-says.
Show me how it is Just?
Show me how it is not excessive?
