Book of Revelation: What do you think will happen?

In my opinion, the book of revelations is just an ending chapter in the bible. For every story it has an beginning and an end. Through the people who wrote the bible since Christianity made developments as an rising dominate religion in the last years of the Roman Empire is mainly just an example of the harsh treatment of Romans who were Christians and every citizen who wasn't a Christian had an mark. This of course is where we get the number 666 or mark of the beast, who was the beast? The Roman Empeiror. So the book of revelations in my opinion is just an example of atrocities made from the Romans and of course like with every begining, there is always an end.
