Hell is justified.

[Abaddon_ire]

"it's similar to what serial killers make their victims live before they die"

And serial killers are horrible people. That's what you're comparing your god to?

God is not human.
Lions tear people and maul them.
Snakes poison children.
The sun burns people alive. But we seem to find the excuse and pardon these non-human entities in doing so.

Why can't we do the same with God?

Your god is supposed to be better than human, isn't he? Perfection, even? And as mere humans we should strive towards your god's perfection, shouldn't we?
Doesn't that mean we should become better torturers?

Torturing humans is very normal when the one inflicting the torture is not even human.

Nope. Now you claim that your god is sub-human.

Our problem is with humans torturing humans.

And that humans have a higher moral standard than your god.
