Don't look back in anger

I fought all night with broken bones,
Stuck in my little world,
Against what I find
A bit too much to handle.
Between harsh words
And silver knife held high
All seemed to sway away.
I had to do, what had to be done,
For the sake of myself,
Or maybe to let you go free.
So don't look back in anger on me,
It's perfectly normal
To murder, what was said.
It's just and courageous
To smash what was left
Of my little world.
