Half The Man I Used To Be

My steel is rusted. My aura doesn't glow. I showed him a gun, my passion refused to fade.

I'm half the man I used to be. Or was I always this much?

I left you too late. I should have never taken your fall. Why did you complete me when I had to leave you?

Now what do I shoot, the half I left or the half I'm left with?
