That's not true.
Universalism, or better, Ultimate Redemption, allows for a full age of judgement/evaluation/correction/restoration.
Every nation, leader (government/religious), and individual will face judgement and accountability.

Ultimate redemption only has one period of grace in which redemption can be obtained. That period of grace only exists while a person is able to draw breath, and it does not extend to an infinite time period after a person draws their last breath like you are wanting to happen.
Genesis 2:17 is best understood that if a person commits a sin against God, that they immediately become a candidate to die the second death in the "distant" future after they are judged at the time of the GWTR judgement.
Now Ezekiel 18 tells us that if a person is a candidate for the second death, then if they repent of their sin(s) and change their ways to honour God in the prescribed manner, then that person will gain eternal life at the time of the GWTR judgement. This chapter also tells us that if a righteous man sins, that he will not live unless he repents of his "sin(s)", but that he will certainly die the second death.
There is no get out of jail card in life which a person can use. The only out for a person to gain eternal life is for that person to repent of their sin(s) during the period of Grace that God allows before they draw their last breath.
Sadly, what you would like God to do is to love you more than anyone else and allow you to sneak into the age of eternity ahead of everybody else. What you are teaching is that God is not fair to everybody else except to just you with your theory of Ultimate redemption.
The rules for eternal life have been set in stone and God has confirmed these "rules" from the very beginning and will not change them just for you and your like. That is what is called fairness on God's part.
You and your like have been given a period of grace to comply with God's prescribed rules and He apparently has no intention of changing them for anybody.
