Remember, the bible was not written in English, and Revelation is a book of symbolism.
You are ignoring many, MANY scriptures that juxtapose the fate of the saved as eternal life and the fate of the unsaved as its opposite - death, destruction, perish, etc.
And frankly, the message of the destruction of the lost fits more with the personality of God. Even in the OT, his punishment was to wipe out entire nations. Even Sodom was not tortured, but annihilated.
God’s past and current dealing with those that are not His involves two courses:
1. Turn them to Him
2. Get rid of them.
You may note that I quoted Revelation in GREEK. Yes, I know that the Bible was not written in English!
Aside from this, see my previous post.
