Metallica - Disposable Heroes

I used to think all the negativity in a song was evil. But I don't know if that is right. Looking through Psalms, I see the Spirit of Jesus Christ singing a lot about his own sufferings.

That being said, I think James Hetfield from Metallica hates legalism about as much as Paul did.

Bodies fill the fields I see, hungry heroes end
No one to play soldier now, no one to pretend
Running blind through killing fields, bred to kill them all
Victim of what said should be
A servant 'til I fall

Soldier boy, made of clay
Now an empty shell
Twenty one, only son
but he served us well
Bred to kill, not to care
Do just as we say
Finished here, Greeting Death
He's yours to take away

Back to the front
You will do what I say, when I say
Back to the front
You will die when I say, you must die
Back to the front
You coward
You servant
You blind man

Barking of machine-gun fire, does nothing to me now
Sounding of the clock that ticks, get used to it somehow
More a man, more stripes you wear, glory seeker trends
Bodies fill the fields I see
The slaughter never ends
