This is why I say the scriptures are contradictory on the doctrine of the final judgment.
Believers tend to choose the ones they prefer and refute the others. To what end?
Ultimately I choose the doctrine that fits my view of the character of God.
My topics on the subject.
Rev 14:9 And another angel, a third, followed them, saying with a loud voice, “If anyone worships the beast and its image and r
eceives a mark on his forehead or on his hand,
Rev 14:10 he also will drink the wine of God's wrath, poured full strength into the cup of his anger,
and he will be tormented with fire and sulfur in the presence of the holy angels and in the presence of the Lamb.
Rev 14:11 And the smoke of their torment goes up forever and ever, and they have no rest, day or night, these worshipers of the beast and its image,
and whoever receives the mark of its name.”
For Universalism the first thing you have to do is to throw Revelation out of your Bible.
Much of Revelation is based on OT passages, I once made a document of that on an old website of mine, unfortunately the links don't work any longer but it gives an excellent impression how much is based on the main OT prophets Daniel, Ezekiel, Isaiah, Jeremy.
For the above 3 verses check out Ezekiel chapter 8 and 9, it's also about people receiving a mark, the ones who escape from a terrible judgement. Some quotes -
Ezech 8:18
Therefore I will act in wrath. My eye will not spare, nor will I have pity. And though they cry in my ears with a loud voice, I will not hear them.”
Ezech 9:1 Then he cried in my ears with a loud voice, saying, “Bring near the executioners of the city, each with his destroying weapon in his hand.”
Ezech 9:2 And behold, six men came from the direction of the upper gate, which faces north, each with his weapon for slaughter in his hand,
and with them was a man clothed in linen, with a writing case at his waist. And they went in and stood beside the bronze altar.
Ezech 9:3 Now the glory of the God of Israel had gone up from the cherub on which it rested to the threshold of the house.
And he called to the man clothed in linen, who had the writing case at his waist.
Ezech 9:4 And the LORD said to him, “Pass through the city, through Jerusalem,
and put a mark on the foreheads of the men who sigh and groan over all the abominations that are committed in it.”
Ezech 9:5 And to the others he said in my hearing, “Pass through the city after him, and strike.
Your eye shall not spare, and you shall show no pity.
Ezech 9:6
Kill old men outright, young men and maidens, little children and women,
but touch no one on whom is the mark. And begin at my sanctuary.” So they began with the elders who were before the house.

Ezech 9:10
As for me, my eye will not spare, nor will I have pity; I will bring their deeds upon their heads.”
Ezech 9:11 And behold,
the man clothed in linen, with the writing case at his waist, brought back word, saying, “I have done as you commanded me.”
From Daniel we know who
the man clothed in linen is.
Isa 34:8 For the LORD has a day of vengeance, a year of recompense for the cause of Zion.
Isa 34:9 And the streams of Edom shall be turned into pitch, and her soil into sulfur; her land shall become burning pitch.
Isa 34:10
Night and day it shall not be quenched; its smoke shall go up forever. From generation to generation it shall lie waste; none shall pass through it forever and ever.
Read the whole chapter, interesting is that the fire eventually went out.
You can argue that OT judgement is only about our short stay on earth, but Revelation judgement is eternal.
