The Anti-Christ for his partnership with the Devil will be thrown into the 'lake of fire with burning brimstone'. This will happen at the Second coming when Jesus Christ will return to defeat the armies of the world who are prepared to battle against Jerusalem and God. His reign will end on that day and his punishment will start for all eternity. He can not be forgiven, neither will there be a respite in his punishment save to stand before God to be judged and convicted of sin.
His life is not one to be envied and his future secure in Hell.
