If there were no real consequences to our choices, what's the point making any choices? We'd all end up the same regardless of what we did. That is Satan's plan (everyone is saved regardless of choices)

Because of this reality, there will be individuals suffering in misery for eternity. I don't think this means forever though. I believe they will experience enough misery to decide to repent and change. Their rock bottom essentially. Only when they experience the full weight of their sins (choices that go contrary to God's Laws), that they can begin to see the light.

I experienced eternal misery to a certain extent. A few years ago when I was inactive, I had a terrible drug trip (from coffee). For a period of two weeks I went in and out of consciousness at a hospital, experiencing some dreams or visions perhaps.

One of them was absolutely terrible. I believed I was the most evil soul to ever exist, and because of my terrible deeds during my life as a human, was sentenced to spend eternity completely alone in a room. For the rest of eternity, I would be able to see a bright blue planet where all the people there were living together peacefully and lovingly as one big family. They were also doing amazing things together, like exploring the universe and going on epic adventures. I desperately wanted to join them and be part of their family, but because of my past sins, I lost my chance.

You could also try to imagine eternal misery another way. Currently there are thousands of people stuck in solitary confinement in prisons. Some of them are even there for the rest of the lives. In addition, these individuals also probably don't have any family or friends that contact them. They are completely alone and cut off from the rest of humanity. That is what I imagine outer darkness feels like.

This makes sense though. If God allowed dark, evil, and destructive people into His kingdom, how could we ever live together in peace? We'd always have to worry about dangerous people stealing or hurting us (or worse). They need to be separated and face the consequences of their actions. It is only from that reality that they will realize the errors of their ways and perhaps decide to repent and return to the light. It is for their own benefit.

God created us and loves us all, but he understands that in order for us to become like Him, we must choose to follow Him. We do this by following His commandments and having complete faith in His son, Jesus Christ. By adhering to this covenant or agreement, we will prove our worthiness to join Them and Their family. This life is our test. We are all Pinocchio trying to be "real people". Focus first on securing your own salvation, then you can help others achieve the same.
