My grey human heart

"My little grey heart, where did you go?
Over here, in the dark.
my little gray heart, where did you go?
sitting here fading away for there is little for me to gain my strength.
my little grey heart, where did you go?
You left me behind, for the blood and vengeance.

You're turning black and white.
Parts have died, and I've become horrified of what I see.
Look what they did to us!
I'm looking, but haven't we done worse?
They all deserved it!
who...? the civilians or the real enemy?

My little grey human heart, why did you go? You had no use for me anymore...

....Even though I'm the only heart you'll ever have.
