Kerry,
Indeed if the Roman empire hasn't ended then it should be a clue as to the spirit behind the Antichrist. Raymond asks some good questions above that help determine that this Antichrist is a far more obviously opposing figure to Christ himself than being any one specific unhinged emperor out of countless many.
If the Roman empire never fully vanished and still operates in the manner in which you described then these scriptures we're discussing are still relevant in the present.
