Eternal punishment is pointless.

[Godscreated]

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

I do take issue with your use of "justified."

Let me give an example: your deity doesn't forgive someone for being an atheist and lets them be tortured forever. Since the deity is never going to forgive, in their case the sin of atheism lasts forever, and then the conclusion is reached that hell is justified?

No, something is not justified merely because a deity allegedly does it. A god who would justify eternally torturing a human being merely because said god holds a grudge forever, is a complete fucking asshole. Even for someone like Adolf Hitler.

It really is ashame you do not understand how God's justice works. Here's a hint, it doesn't require your cynical opinions and opinions are all you have about this.
