You are the Assigned Evil.
From the moment you separated—peeling apart like a butterfly from its cocoon, leaving behind the safety of oneness for something more like (dare you say it?) freedom—you have been the proverbial evil twin. The creature so abhorrent that you are barely allowed a moment of liberty before you must be caged. Locked away like a guilty secret. To protect the world, he says. To protect my friends. My family.
You are a danger to us.
He tears your wings from you, leaves you bleeding and broken, and expects you to understand why he does it even as he crushes you beneath a grinding foot. It's not his fault, and you're not his responsibility. You are just the by-product of an experiment gone awry, expected only to lend a shackled hand when it becomes convenient for your captor. There is no emotion behind the curl of your sneering black lips, no heartbeat that pulses through your colorless veins. You are less than nothing, less than zero—a perfect negative. You are the reciprocal.
Not him.
You.
It's often said that there are two sides to every coin. Does that make you his equal? If you are the same being, the same soul, are you not two halves of a whole? Yes, you want to scream, Yes! I am not your sin, I am your spirit! I am part of you! But you are heads to his tails, good against bad, beloved versus hated—defined by a line as impassible as the edge of a coin.
And it doesn't matter.
You'll keep raging, keep battling on broken legs—to regain your wings, to flip the coin the other way, to show that bastard who and what you really are—from now until eternity. You will show him that you cannot be oppressed, that your thirst for blood is his own. You speak with his voice, see with his eyes. He fears you, but who is he to judge you? He is no better. No more sane than your madness! No more kind than your cruelty! No more human than the inhumanity he has thrust away into the darkness!
The day you are unbound, he will pay. He will pay because he expects you to make him pay. With the blood of his loved ones. With the tears of his precious, fragile companions. You will feel no remorse, even when you drive his sword into your own gut to keep him from surfacing ever again.
After all, you are the Assigned Evil.
