Pull the trigger

My pistol is loaded,
My mind full of hate,
Your heart full of innocence,
You think...
But somewhere you know that you hurt people,
I know some people don't deserve to live,
You are one.
I walk to your bedroom,
and open the door,
There you are sleeping,
Like you have nothing to fear...
And I'm laughing inside
Because I know that when I walk out your bedroom door,
You will never wake up again...
