Mild hijack, but I don’t see how wiping the Borg out would necessarily count as genocide. It’s not like they’re one species, and the only reason that they have the same “creed” is because they’ve been surgically altered and brainwashed. I don’t recall any reference to a civilization joining the Borg voluntarily. I wonder how that scenario would play out:
SCENE: THE PRESIDIUM OF THE PLANET HODAG, SURROUNDED BY BORG CUBES
BORG COLLECTIVE (V.O.): WE ARE THE BORG. YOUR BIOLOGICAL AND TECHNOLOGICAL DISTINCTIVENESS SHALL BE ADDED TO OUR OWN. RESISTANCE IS FUTILE.
PRESIDENT OF HODAG: Okay!
BORG COLLECTIVE (V.O.): **PREPARE TO BE ASSIM… …WHAT? **
PRESIDENT OF HODAG: (WITH HUGE GRIN) Come on down! We’re all ready to go!
BORG COLLECTIVE (V.O.) YOU… DESIRE ASSIMILATION?
PRESIDENT OF HODAG: Sure do! Greatest thing since sliced bread! Let her rip, Chalky! What’re you waiting for?
BORG COLLECTIVE (V.O.) ER, WE… WE’LL GET BACK TO YOU.
–Anyhoo, seems like the Borg is more like a virus than a legitimate species. Otherwise, removing those implants from Picard would have have amounted to murder, yes?. The essence of “Borgness,” then, is the technological crap and the forcibly implanted message to spread it to others like the flu. Killing off the Borg with the Escher print would have been wrong not because it was genocide, but because it would have also killed the “hostages”-- the former individuals enslaved to the Group Mind, who might one day be liberated in the same manner as Picard.
