My dark side

My demon is coming out
Scratching and biting
Never saying anything else
It only pleases itself
Never taking in anyone else
What ever it touches doesn’t come back
I’ll cut you up and spit you out
You think I’m lying
But try me out
Every night I get out
And take the lives of the right
And the toll is the souls
That will never come home
And the day is coming
When I will ruin myself
