FYI... the two individual humans we know from Scripture that will definitely occupy Hell - Judas Iscariot and the Antichrist.
Antichrist is "instead of Christ". It is the role Satan assumes when he comes to earth pretending to be Christ. Jesus warns us about him in His Olivet prophecies.
Mark 13:14 But when ye shall see the abomination of desolation, spoken of by Daniel the prophet, standing where *it ought not, (let him that readeth understand,) then let them that be in Judaea flee to the mountains:
*it should have been translated as (he)- it is an entity, the desolator, not desolation. His number is 666 - he comes at the 6th seal, 6th vial and 6th trump.
At the 2nd Advent that role of Satan, as anti-christ (instead of christ) and the beast (religious beast) were both thrown in the lake of fire:
Rev.19:20 And the beast was taken and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
The mark is to follow him, to believe he is Christ. Both roles are done away with but not Satan himself.
Rev.20:2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,
And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
Rev.20:7-10 tells us that when Satan is released he tries to deceive again, and many will follow him, but only for a short time as God "devoured them". They are cast into the lake of fire.
Some believe that lake of fire is a place where one is tortured forever while others believe it is a Hebraism that means they are blotted out - gone forever and ever.
Judas Iscariot is a different story. In Matthew 27:3, "Then Judas, which had betrayed Him, when he saw that He was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders.
4.Saying, "I have sinned in that I have betrayed the innocent blood," And they said, "What is that to us? see thou to that."
5.And he cast down the pieces of silver in the Temple, and departed, and went and hanged himself.
When we go to Acts we see that he had a lot of help in hanging himself -
Acts 1:18 Now this man purchased a field with the reward of iniquity; and falling headlong, he burst asunder in the midst, and all his bowels gushed out.
It sounds as if some of those "religious" folks at the temple didn't want the whole story to get out so had Judas slit open and then hung. (something to think about)
At the same time we must realize those that killed Christ were not truly Jews. The chief priest was not appointed by God but by the Roman governor. They are the ones Jesus referred to when He said :
Rev.2:9 ....I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.
Our brother Judah is not to blame for the death of Christ.
Satan is the only one that has been condemned, by name, to death. The fallen angels have also been condemened and will die upon Christ's 2nd advent. Judas repented and as terrible as the act was he committed, it is still not the unpardonable sin. What happened had to happen - it was why Christ came to earth. God judges.
