  • Heather Jarman's main inspiration for this story was her undecided opinion of the United States of America's War on Terrorism. She commented "Ultimately, I concluded that peace isn't the absence of war, that there are times and places when war is justified and moral. But I did wonder about whether or not there's a "moral" way to conduct a war or whether the ends did justify the means when it came to confronting an enemy. If the enemy was ruthless, were you justified in being equally ruthless? At what point do you become your enemy and lose the moral high ground?" (Voyages of Imagination)
  • Andrew J. Robinson listed "The Devil You Know" as being one of his favorites from the Prophecy and Change anthology. This praise made Jarman come to think of it much more favorably, as she felt it was a difficult project. (Voyages of Imagination)
  • In her review of the anthology, Jacqueline Bundy commented "Just like many of DS9's best episodes, "The Devil You Know" is a thought-provoking tale. Grief, anger and frustration are powerful emotions and this dark tale reminds us that when in the grip of such strong unrelenting feelings, it is very easy for an individual's moral or ethical boundaries to shift".
