What happens to the Antichrist at judgement?

This one's been bugging me because there's a few paradoxes. Does the antichrist get to choose to be the antichrist. If he does, what happens if the antichrist chooses not to follow that path, and if he doesn't, won't that interfere with God's plan of free agency. Following the "if he doesn't" train of thought, maybe there is some immunity to the judgement, since he didn't choose to be evil, but was part of an plan. Just wondering what everyone's opinion is.
