The whole song is in Bmajor, chordwise and keywise.

The bass plays three different riffs:
Riff1:
G--------------------------------------
D--------------------------------------
A--7b9b7----6--------------------------
E--------------7--7--7--7--7--7--------

Riff2:
G--------------------------------------
D--------------------------------------
A-7-7-7-7-6-6-6-6----------------------
E-----------------7-7-7-7-7-7-7-7------

Riff3:
G--------------------------------------
D--------------------------------------
A--------------------------------------
E-4-4-4-4-5-5-5-5-7-7-7-7-7-7-7-7------

These are basic structures of the song, there is a lot improvisations,
so listen to the record.
Riff1 is in intro and under first parts of the verses, then comes Riff2
to bring up the intensity, then back to riff1.
Riff3 comes in with shriekieng guitar chords that are tabbed below.

Guitar:
Plays a Bmajor-chord at seventh fret(799877)all through song, with     
various arpeggiates.
Some are more repetetive than others, examples:

e------------|-------------|
B------------|-------------|
G------------|--------8----|
D------------|---9--9---9--|
A-7b9b7-6----|-------------|
E----------7-|-------------|
 ^played in   ^played in
  intro and    second verse
  begginning   When guitar
  of verses    comes in

Otherwise just improvise arpeggiating different B-chords.
Theres a lot of two guitar solo in there, and the lead guitar plays solo
during the whole song. I like to just improvise in Bmajor scale and see
what I can come up with. Even though it never sound as good as the
record, it sounds ok. I use a lot of loooong slides, biiiig bends and
harmonics to get the right feel.

The shriking chords that comes in when Greg sings "to see you were alive
instead of watching you abandoning yourself" and in outro is this:

                        Hammer-on/pull-off the last 11(12)

lyrics
    
     Baby, I see you've made yourself all sick again
     Didn't I do a good job of pretending?
     You're saying that the victim doesn't want it to end
     Good. I get to dress up and play the assassin again
     It's my favorite
     It's got personality
     I should have seen this shit coming down the hall
     Every night I spent in that bed with you facing the wall
     If I could have only once heard you scream
     To feel you were alive
     Instead of watching you abandoning yourself
     Baby you can open your eyes now
     And please allow me to present you with a clue
     If I inflict the pain
     Then baby only I can comfort you
     Out of the night we come
     And into the night we go
     If it starts to hurt you
     Then you have to say so
