The dead rich man in the story that Jesus tells is in that lake of fire and isn't destroyed. He's talking and asks for mercy. (He is of course refused) What's the point of saying something like "Now he is comforted and thou art tormented" if rich greedy men aren't being tormented in the after life?
Again, see my arguments about this story being a parable. There are a number of passages where Jesus uses similar apocalyptic and destructive language to refer to make a point. You can take this literally if you want, but it's not atypical of rabbis of the time to use extreme language to make a point.
You are essentially asking a question of why ANE cultures communicated as they did. We can discuss that, but it's not just a simple, "If he said it, he meant it." situation.
Additionally, even if it is. The main filter Jesus seems to use for who gets punished and who doesn't is NOT any kind of "faith" that we seem to advocate for here in America. Almost every situation is about the rich and powerful hoarding wealth and the expense of the poor. The rich man and Lazarus, the sheep and the goats, the rich man, the eye of the needle, etc.
So EVEN if there is punishment it's not about if you profess to be a Christian or not, but how well you treat those around you with the resources you have - if we take Jesus literally.
Still if it is a place for people to get destroyed, that doesn't make the argument of the thread a whole lot different. That's still really awful. People have to be okay and be able to sleep with worshipping someone that is destroying their loved ones and billions of others for not believing in him. I don't see how anyone could be okay with that.
The argument by many theologians and Christians is that the fire is not about "destruction" but about cleansing. It's about the impurities being burned away so that the "good essence" is left remaining.
There's a phrase I believe C.S. Lewis coined, "the gates of hell are locked from the inside." The idea is that anyone, at any point can chose to join in heaven, but they willingly opt out. Most of Jesus parables talk about people who are so hard hearted they want nothing to do with the celebration that invites all the people they don't think deserve to be let it in - so they opt out. Jesus seems to imply that people shut themselves out of the party, not that God tortures them.
My point is there is a huge number (though perhaps not the Evangelical majority) that DO NOT believe that the Christian God will send billions to hell for not believing in him. It's tough to explain because so many people that have a beef with Christians haven't been given the best theological foundation to be able to recognize that the arguments made are not just people trying to make it palatable, but actually have a case based on hermeneutics, historical understanding, metanarrative arcs, and historical perspectives.
I don't blame you for not wanting to do the work for something you don't believe in, that's fine. But trust me, I am a Christian and I do not espouse the perspective you claim we have, nor do thousands of others I've met with.
I can make a lengthy case for this, but don't have the time to summarize a number of books.

For a group that claims to know the meaning of life and death there sure is a lot of uncertainty and vague language about any claims made whatsoever.
Where do they claim to know the meaning of life and death? Christianity only claims that Christ defeated death, not that they understand every nuance to the cycles of life and death.
Even Dante, who we probably got more ideas of hell from than the actual Bible had some pretty open ended views on judgment:
Dante, who mentions Trajan in Purgatorio, X and Paradiso, XX. By Dante's time, there was a legend in wide circulation which goes roughly as follows: Trajan was all set up to take his army to war when a poor widow came up to him and begged him to avenge her wrongfully slain son. Trajan agreed to do so, holding up his campaign in the process. Centuries later, Gregory the Great (pope from 590-604) was so impressed by this that he prayed that God would resurrect Trajan and give him a chance to accept Christ. An angel came to tell Gregory that God had granted his prayer, but commanded him never to make such a prayer again (!). Thus Dante, incorporating this tale of faith and "coinherence backward in time" into his comedy, gave Lewis an illustration to use in a story where the lost can become saved (by His grace) if they choose.
Or the Christian darling C.S. Lewis:
In The Last Battle Lewis pictures the Emeth (The Hebrew word for Truth) as a Pagan (like Trajan?) who mistakenly followed Tash without knowing the true Aslan until the end. That, however, is a rich, suggestive image that deserves another paper. The idea behind this is that one orients oneself to Heaven or Hell by getting on a road that leads from or toward God. And the horrible thing about this is that one keeps traveling this road, growing farther away from God or closer to him for all eternity.
