I think you guys are close, but not not 100% on the money here. Ive overanalyzed this song im sure, since it was my favorite for quite a long time- but here's my take on it all:

He's clearly stalking this girl he's obsessed with. She doesnt love him back, and might even be making fun of him (...heard what you said and you're laughing baby...). He cuts himself as a form of emotional release/self mutilation and all. The "see you in hell" part, i think, is because SHE dies- and he killed her. He's saying he'll see her in hell when he finally dies. The clincher for me on this idea of him murdering her is how the last solo trails off and then builds up and gets faster and faster... thats when he goes off on her and kills her in a moment of chaotic insanity.

At least thats my take on it.
