Going AWOL.

He ran away from the army
Went, what the officers call, AWOL
And got executed for it
For being an unpatriotic arsehole
'Cause if you say you're gonna kill
Then boy, you better bag a corpse
And when a leader barks an order
Your answer must be "Yes, of course"
Otherwise you're using free will
That thing that makes us who we are
That thing that must be obliterated
Before it leads us down the wrong path
