The "wicked" or "filthy" is the 4th state
Rv 22:11
1 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.
Who are the filthy? Simply fallen unredeemed man from what I could find, in case it helps here:
Job 15:16
How much more abominable and filthy is man, which drinketh iniquity like water?
Psa 14:3
They are all gone aside, they are all together become filthy: there is none that doeth good, no, not one.
Psa 53:3
Every one of them is gone back: they are altogether become filthy; there is none that doeth good, no, not one.
Isa 64:6
But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away.
Zec 3:3-4
Now Joshua was clothed with filthy garments, and stood before the angel.
And he answered and spake unto those that stood before him, saying, Take away the filthy garments from him. And unto him he said, Behold, I have caused thine iniquity to pass from thee, and I will clothe thee with change of raiment.
The unjust are being compared with the righteous (who are just/redeemed), and the filthy are in comparison with the holy (who are clean/pure/redeemed). Scripture very often conveys a single idea in couplets I think it is called (?)....saying the same thing in two different ways.
