I think this song is about the basic urges/driving forces that we all have as humans. The "devil" represents the personification of our negative or "evil" urges and actions. It's too hard for most ppl to admit that evil lives inside them, so they instead use a made up entity, the devil, to project their evilness onto (separates ppl from the undesirable parts of themselves). SO, "I am heart of the devil" means that mankind is the creator of and the driving force behind all things evil (heart keeps us alive, just like mankind keeps evil alive in the world). "I have heart of the devil" references the negative desires that are inside all of us; they come from within our heart/driving force. The rest of the lyrics could be symbolic examples which show mankind's propensity/capability to be "evil" (killing others; sex with unacceptable partners--"I can make a young girl lay down for me"; drugs--"I can make a pulse pound in your vein"; threatening or scaring others--"...man freeze in his tracks"; war--"I can make the skies thunder and shake...world tremble and quake"=bombs, missles, jets, etc.; medical advances "heart stop and start again"= through medicine we can kill ppl or bring them back to life. I think Danzig is calling out ppl who have not yet came to this realization.
