When God "does" things on earth that we humans clearly see as unfair, Many Christians are quick to say, God works in Mysterious ways, that there is a meaning for everything, that they are lessons learnt etc, and that we cannot comprehend what God does and we should never question it.

That's all very well.

If God sends well deserving Christians to "hell" that, I guess those Christians will say the same thing as they burn away with Satan.

How dare you question God for sending you to hell, he knows best what you deserve. How clever of God, don't you all agree.
