You are correct in putting different scriptures on the outcome of the Antichrist together. We cannot cherry pick one scripture and deny another.
In addition to the scriptures you mention there is also the final outcome where everyone who is not with God, will be in the outer darkness, where there will be weeping and gnashing of teeth.
Revelation 22:15 describing they without must also be by synonomous with the outer darkness and lake of fire.
Revelation 22:15 For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
I don't think darkness is a place. I think it's a state people are in,
He that saith he is in the light, and hateth his brother, is in darkness even until now. 1Jn.2:9
But even until now, those in darkness may come into the light through Jesus. So "outer darkness" can mean a persons state of being unsaved is permanent and this judgment may cause tears and wailing without the tears and waIling lasting eternally.
It's interesting that passages about "outer darkness" have to do with hypocrisy. John says that without are murderers, sorcerers, etc. Doesn't that go without saying? Could it be people think they're saved, but they're not,
Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him. 1Jn.3:15
So Jesus said,
But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire. Mt.5:22
I mention these things because the passage you fired says,
He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still.
Rev.22:11
In other words, how we are now, is how we will be seen later and Jesus tries not only people's works, but people themselves.
