Stunning, especially the last question.

This is a fascinating section of your work -- I'd love to see more rather than just this.

However, this is powerful.

This stanza is awesome:

"Denied!" I shout. "You make me watch them,
evincing their promises when I know,
surely know, death takes them all.
That is love, hope in the face of tragedy.
I am denied this, why?
Not for my crimes, but my creation?
You, hear me for the first time!
Salvation should be my choice as well!"

This line
"Even they," I say, "lesser creatures, create.
should they be then?

So now we approach clarity even more. My religious tradition teaches us that there is one Creator. However, each of us individually must create our own image of the Creator. Know then that this is no dialogue, it is an internal monologue. Therefore, you (and Regan) have the power to change this discussion. Once this is understood, the undertone of a victim's self pity will vanish. My Creator, whom I believe may be totally indifferent to me, gave me what I need to survive. That includes the ability to love and to be loved.
You might need to change this discussion. You may not have created a complete image of your Creator. The Creator is not limited by the limitations of those created. In fact, Salvation not only "should be" your choice, it really is. And so this wonderfully written internal dialogue creates in me compassion and annoyance....and a great deal of interest.

P.S. I remember King Lear had a daughter named Regan. I thought it was a woman's name.
