It 'sounds' like you are saying that the writer(s) did not intend for collection of scenes to be entirely compatible with each other, and thus there was no attempt to predict any specific outcome (other vindication and vengeance). But I wonder if the writer(s) were presenting what they thought were a collection of possible futures, thinking that one of them might be the actual future. But perhaps they were merely trying to convey that no matter what evils the government(s) will do to Christians and no matter what badness is done by individual people, in the end God will vindicate faithful Christians and carry out vengeance those those deemed bad.
Some scholars (at least James Taylor) say the vast majority of the content of Revelation was written by a non-Christian Jew, but that a Christian later added content containing Christian ideas. Tabor at https://jamestabor.com/here-it-is-at-last-a-pre-christian-version-of-the-book-of-revelation/ mentions what he considers the non-Christian Jewish version of the text. That web page has a link to a PDF file of his text. At https://jamestabor.com/here-it-is-at-last-a-pre-christian-version-of-the-book-of-revelation/ Tabor says the following.
"The thesis of the post is a simple one. Behind the New Testament book of Revelation, formally called “The Revelation of Jesus Christ,” (Rev 1:1), is an older Jewish apocalyptic document that had nothing to do with Jesus or the early Christian movement. The additions, or interpolations, made by a later Christian writer, are potentially identifiable, as is quite often the case in such Jewish texts that have a Christian overlay.
...The name YHVH/Jehovah has been inserted in places where the use of the Greek word “Lord” (kurios) is clearly the Divine Name. Otherwise “Lord” in this text is taken as the Hebrew word ‘Adon (see Zechariah 4:14)."
