Well to be the Antichrist you must be corrupt for sure, however when you reach the point of being against christ and you lost all reason, in a desperate state of despair (which comes after terror) I would call you a Antichrist. However, the point is that how can you be against Christ when its the same as the Antichrist, that would be like being against yourself. I might be the only one in this but I dont see Christ as the Christians claim it to be a good spirit. It must be balanced to teach such things for it is only a teacher or perhaps a messenger. I believe when all have left you, in the state of utter darkness, you are more than corrupt, being against everything and finally only the Self must be left. I dont think humans can reach this point, but through pain and loneliness you might come very close...
