I am an angel...

I am an angel.
What I fell from the sky.
I searched everywhere.
But in heaven I do not I found.
And I decided. You look here on earth.
If not you will not find me here.
I descend into hell.
Perhaps there I will find.
If not you will not find me there.
I will turn into a demon.
And will destroy heaven and earth.
Still hoping that somewhere.
I find you I will.
