It’s From the Sleep Deprivation.

I always forget my role.

Am I the angel that saves sinning souls? 

Am I the demon and corrupting 

people is my goal?

Could I be a God, creating rules as problems pop up?

Ah, now I remember. I'm the human, trying my hardest not to run out of luck.

Living life, constantly toeing the line.

I don't know if Heaven will take a soul as dark as mine.

But hey! I remembered. What, is forgetting a crime?

Yes, I remember; I'm the mortal, living on borrowed time.
