Well. I suppose if the singer implicates himself as the persona in the song, then he is an antichrist. Most probably a devil worhipper who's now at the verge of death. Most devil worshippers know the knitty grittys of hell. While alive, he 'used to rule the world because probably he had so much power that he could do anything. For instance, with the power, he could kill anyone, or do whatever he wanted to anyone and get anything he wanted. 'seas would rise when I gave the word. Feel the fear in my enemies eyes. ' is an example of how mighty his power was. But a mortal is not held in respect in the eyes of satan, (nor of God anyway). Now that he's dead he knows that saint peter wont call his name. I. E he wont go to heaven. So in hell, he is not respected at all, he sweeps the streets he used to own and he is lonely there. With all the power he had while on earth, people can't believe he is a slave in the satan's kingdom. 'people couldn't believe what I become'. His head being waited in a silver plate shows his ultimate downfall from an earthly emperor to a slave in the satan's kingdom at his death where he has no chance to change his life. (you can do anything to a head on a plate).
