Don't make me kill you again

I didn't want to do it the first time, but they said it had to be done.
I didn't want to do it a second time, but you decided to run.
I don't want to do it a third time, so why not sit there and act dumb?
I'm running out of money & I'm running out of guns.
This job is definitely becoming unfun.
Don't make me kill you again.
