First you would have to go back to my post #19 and follow my advice there.
To track the villian, you have to have a timeline framework to know when he is the beast, the Antichrist, the littl horn, etc. Which my post #19 gives the structure of the chapters in Revelation. Not as though you are new to Revelation though.
That was to give a practical example to the other poster.
In your case, just tale a look at the structure information from Chapter 6 to 19 that I provided in that post.Regarding the villain being the beast in Revelation 17:8, you have to look for connections elsewhere in Revelation... Chapter 13 is the chapter regarding the beast being killed and come back to life and everyone worship him in the end times.
Revelation 17:8 tell us that the BEAST whose everyone SHALL WONDER whose names are not written in the book of life of the Lamb will COME OUT OF THE BOTTOMLESS PIT.
Which refers to Revelation 9 .....Revelation 9:11
So do you believe in reincarnation? I don't. So the beast in former times is not going to be reincarnated in the end times. The only other option I know of is the beast in former times, is now a
disembodied spirit, that will be allowed to come out of the bottomless pit
and possess the end times person - earning the possessed endtimes person (when he appears to have cheated death) the label of being the beast.
The Beast who shall ascend out of the Bottomles pit is not a disembodied spirit that is a fallen angel.
Revelation 9:11
11 And they had a king over them,
which is the ANGEL of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon.
Angels are immortal [The Beast wounded at the head came back to life Revelation 13:3-8]
Revelation 13:3-8
3 And I saw one of his heads as it were wounded to death; and his deadly wound was healed: and all the world wondered after the beast.
4 And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?
5 And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.
6 And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.
7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
8
And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the
world.
Revelation 17:8
8
The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition:
and they that dwell on the earth shall wonder, whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is.
Revelation 11:7
7
And when they shall have finished their testimony, THE BEAST THAT ASCENDETH OUT OF THE BOTTOMLESS PIT shall make war against them, and shall overcome them, and kill them.
