Eternal punishment is pointless.

[Cyberman]

Remove the god and you remove the sin.

How do you remove the God that's eternal, one with no rival?

Very easily. I do it all the time. I'm doing it right now, in fact. 'Sin' is a brand name, which you are defining as a 'crime' against "God". I subscribe to no gods, certainly not yours, thus cannot be accused of 'sin'. That's not to say I'm immune to all the weaknesses and strengths, all the passions and the pain, intrinsic to the human animal. However I am no worse than most, better than some, just like everyone else. I have never intentionally hurt another person, especialy not for personal gain. My only 'crime' is not automatically believing your claims about mythology as real.

This god, were it to exist, must be a perfect idiot not to realise that the highest act of love towards its creation would be its own extinction, to eliminate the poison of its effect on the humans it professes to wish to save.

God did sacrifice His life so that everyone could be saved, however that salvation couldn't come without His resurrection.

And then popped right back up again like some hideous Whack-A-Mole, giving clergy throughout history the most potent weapon with which to control the great unwashed through fear of the dark.

All men die and only an omnipotent God can call us to life, saved because of His love for us.

And like I said, if this god truly existed and truly loved its creation, it would surely render itself nonexistent rather than continually poisoning that creation with its presence and fear thereof.

Put it this way. If I came to the realisation that my existence was causing the people around me to suffer and die, I would sooner die myself than be party to the continuation of that suffering. And since you're defining 'sin' as a 'crime' against your god, then fuck that god and the camel it rode in on.
