Well, universal salvation doesn't necessarily teach there is no suffering at all after death . . . but that all will eventually be saved.
"God is not one who requites evil, but He sets aright evil."
-St Isaac the Syrian
Your comment "all will eventually be saved" reminds me of one of my ideas about what happens after you die. See the section below in bold:
I have an idea that when you die you have the opportunity to go into the light and experience God's infinite beauty. We become so enamored by God's infinite beauty time ceases to exist. We melt into God's mind experiencing eternal heavenly bliss. Experiencing the face of God in all it's infinite beauty is the greatest possible experience by definition. Nothing is more penetrating into our core being of experience than experiencing God's infinite beauty. You will experience the greatest possible depth of feeling of unity and oneness with the utter total complete perfection that is God. Why would you ever want to continue to experience time after experiencing God's infinite beauty?
For whatever reason, which is kind of mind boggling in a way, some people choose to turn away from going into the light and experiencing God's infinite beauty. The most compelling reason why someone would turn away is each of us is our own greatest critic. God's infinite beauty and light is a mirror showing us the very worse aspects of our own character. It's only when we are capable of loving ourselves in spite of all our own imperfections that we are capable of not being driven away by the demons of our own creation.
For people who turn away from God there are two paths. One is the short path. One is the long path. First, we will start with the long path. With the long path, after your turn away from God, you choose not to participate with what you are experiencing. This is a very nihilistic way of being. At that moment the person chooses to turn away from God and stop participating with the Universe in a kind of suicidal rage against being itself, the person is immediately given the power of being omnipotent.
Now some of you may be thinking, gee, you die, you turn away from God, you make blasphemy against all of existence by choosing to be a nihilist, and you get rewarded with the power of having omnipotence. This may sound unfair if your heart is immature and you take pleasure at the thought of sinners suffering. Or maybe your heart is full of hate and you are seeking revenge against people who have sinned against you. Or maybe you are jealous and envious of someone else having more power than you do.
But from our omnipotent all-loving God's perspective, our God of unconditional love, what better way to win over someone you love so absolutely and completely than to perfectly give them everything their heart desires. The real sad thing is why would you ever waste any time at all with petty profane desires when you can be looking into the face of God basking in the glow of heavenly eternal bliss. Nothing we can imagine could ever come close to experiencing God's infinite beauty.
Now at first having omnipotent powers may sound like a really good thing. But after millions and millions of years, or what just seems like millions of years, which is only nanoseconds real time, living out all your petty profane desires and imaginations you will become extremely bored. Your mind will have exhausted every possible thing it is capable of imagining. Every possible conceivable scenario of experience you are capable of imagining will have been played out millions of times over. After having sex with two chicks 10,000 times is probably enough. Eventually you will decide there's no point in turning away from God any longer. You will decide with having absolutely nothing left worthwhile to do you will turn back and look into the face of God. However, this time you don't look away. All the reasons forcing you look away before have been resolved during your stint with having omnipotent powers. And just after you look into the face of God you have a very brief thought where you think, “What the heck was I thinking when I turned away the first time?” Time will then cease to exist and you experience eternal heavenly bliss.
Or, instead of choosing the long path, you may choose the short path back to God. Short path is based on what happens to you in the Tibetan Book of the Dead. Essentially, what happens after you turn away from God, is you go down a path towards reincarnation. This is not an easy path to travel down. All along the way there are demons that get created based on who you were in life that are the exact manifestations of everything you would find to be the most terrifying or would cause you the most suffering imaginable. After each encounter you will have a moment or two to find peace and forgiveness from within and choose to finally turn back into the light and face God directly. However, if you continue to decide to turn away from God you will face every possible demon you could possibly suffer from experiencing until you are reincarnated to someone living in New Jersey. When you live in New Jersey there is only Heaven. And the endless cycle of life, suffering, death, and rebirth in New Jersey continues until you finally learn or decide how to appreciate God with the greatest possible faith imaginable and have absolute reverence for God, God's creation (including New Jersey), other people, people living in New Jersey, and yourself.
