Eternal punishment is pointless.

[Chad32]

For an all-powerful God to eternally punish a human is not so much vengeance as just pure malevolent sadism. Like a child with an ant farm who enjoys roasting the ants in a fire, just for being ants.

An all-powerful God who would oversee eternal torture in Hell for finite offences, as "sin" somehow conflicts with his "holiness", is really a sadistically sick puppy and quite a psychopathic tyrant deity, when you really think about it.

Why oh why do so many religions worship and glorify a God like that, who sounds like a much worse asshole than the likes of Hitler?

If God is such a (as you put it,) sadistic being, why would He wait for people to die to torture them, what fun would it be to torture the dead when He could torture people while they are living.

Sin is not finite, unforgiven it last forever, thus the justified eternal hell.

Sometimes he doesn't wait. Ever heard of that one guy who did everything right, and still got tortured on a bet? Then we're expected to believe everything is all better since he gave the guy twice as much as he had. Of course all trust would have been lost between Job and Yahweh, and he probably spent some nights wondering what the point of worshiping someone is if he could screw you over at any time anyway.

Then there are the claims that Yahweh sends natural disasters to areas, whether there are good christian folk or not, because some of them aren't worshiping him properly. There's an atheist in this town. Let me send a tornado to wreck everything, including the lives of my followers, with no promise that they'll get rewarded twice over in this life.

The idea of them becoming more miserable in sin really depends on the sin. Yahweh has a problem with homosexuality, but if two men fall in love, and live their lives with that love, and the community doesn't ridicule them for it, they wouldn't become more miserable. Yahweh smiles on people going on a murderous rampage, killing people who don't follow him, but calls the love between two people of the same gender an abomination. Your god is messed up.
