Down to Earth Gun Them All Down Lyrics

why is it so hard to understand this?
our lives are torn apart
i just can't stand it
gun againnst my head
finger on the trigger
chances of taking my own life
getting bigger and bigger
why should i care?
you tell me life ain't fair
You're full of s___
hand on the gun
finger on the trigger
chances of taking my own life
getting bigger and bigger
i'm sick of all your lies
line 'em up against a wall
and gun 'em all down
