The first one
I killed was by mistake
The second
Infected by the snake
Delusion 
Set in after the third
I'm losing track

My heart is black
My blood is cold my skin is pale
My heart is black
Now follow me on my black trail
My heart is black
My eyes are wide my hands are nailed
My heart is black 
I'm leaving now
The plan has failed
Follow me I know the way

I'm only
shadow of myself
I'm lonely 
What have I [bad word] I'm falling 
Back down the steps I climbed
I'm going back

My heart is black
My blood is cold my skin is pale
My heart is black
Now follow me on my black trail
My heart is black
My eyes are wide my hands are nailed
My heart is black 
I'm leaving now
The plan has failed
Follow me I know the way 

If you don't a fight with me
Leave silently 
But never turn your back on me
