I agree with David Chilton on that from his book Paradise Restored: "As we have already seen, the Caesars were gods. Each emperor was called Augustus or Sebastos, meaning One to be worshiped; they also took on the name divus (god) and even Deus and Theos (God). Many temples were erected to them throughout the Empire, especially, as we have seen, in Asia Minor. The Roman Caesars received honor belonging only to the one true God; Nero commanded absolute obedience, and even had an image of himself built, 120 feet high. For this reason, Paul called Caesar "the man of sin"; he was, Paul said, "the son of destruction, who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, displaying himself as being God" (2 Thess. 2:3-4)." https://www.garynorth.com/freebooks/docs/pdf/paradise_restored.pdf

But it says he takes his seat in the Temple “of God” - that’s a very specific temple lol so yeah if Caesar’s set up temples and call themselves gods that’s fine- but this guy is gonna do it in gods temple, the church.
And he will be revealed after the Great Apostasy and Christ will destroy him at his coming w the breath of his mouth.
Caesar may be a type or shadow, of the spirit of Antichrist, heck later on the bishop of Rome/pope became one for Luther
