The Witch Collector explores what defines good and evil, challenging readers to question moral certainty and the reliability of initial judgments. Through Raina’s evolving perceptions, the novel reveals that good and evil aren’t fixed binaries but shifting constructs shaped by knowledge, intent, and perspective.

At the novel’s outset, Raina believes that she understands what’s good: freeing her sister and killing the Witch Collector and the Frost King, whom she sees as tyrants. The annual ritual of taking Witch Walkers seems cruel and oppressive to her. Equating vengeance with justice, she believes that her violent plan will right past wrongs. However, her perception shifts when she learns that Witch Walkers aren’t kidnapped but willingly serve the Frost King to defend the Northlands against greater threats. Her early desire for vengeance is rooted in grief and incomplete understanding. Had she succeeded in killing Alexus or Colden, she would have caused harm under the guise of moral righteousness. The novel thus emphasizes that evil isn’t always born from malice; it often emerges from ignorance.

Raina’s shifting views of other characters underscore this complexity. She initially believes that Rhonin is a traitor and is responsible for Helena’s suffering. Later, she learns that he’s a Northern spy, working to undermine the Eastlander regime from within. Her misjudgments highlight how quickly assumptions about good and evil can calcify, particularly when shaped by trauma. Raina’s growth lies in her willingness to revise those assumptions as she gains clarity. The Witch Collector suggests that understanding and empathy are prerequisites for moral action.

By contrast, the Prince of the East is a foil to these nuanced character arcs. He embodies a form of evil not circumstantial but absolute. His actions—murdering innocents, manipulating life and death, consuming souls for power—aren’t morally ambiguous. He violates natural law by siphoning the life force of others, even stealing magick from unwilling participants to fuel his immortality. Unlike Raina, whose actions are tempered by evolving self-awareness, the prince chooses domination and cruelty with full knowledge. His evil is systemic, intentional, and self-serving.

The prince’s contrast with characters like Alexus and Colden further reinforces the theme. Though both men carry dark pasts (Alexus as Un Drallag, who created the God Knife, and Colden as an immortal warrior cursed by gods), their guilt and attempt at atonement distinguish them from the prince. Alexus, in particular, bears his burden with humility, tying his life to Colden’s to ensure his loyalty and working to undo his past wrongs. This act of self-sacrifice and his willingness to relinquish power (evident when he offers to undo the rune binding Raina to him) suggest that goodness is less about purity than about accountability and intention.

Moreover, the novel challenges the idea that evil is inherent by revealing the gods’ backstories. Asha and Neri, once divine beings, committed morally questionable acts (Asha drugged Colden to manipulate his affections, and Neri cursed lovers out of jealousy). Their choices brought chaos and divine punishment, blurring the distinction between gods and mortals regarding moral fallibility. This divine fallibility mirrors human complexity and reinforces the novel’s suggestion that power doesn’t exempt one from moral responsibility.

The Witch Collector asserts that goodness arises from humility, understanding, and the willingness to defend others, even at personal cost. Evil, by contrast, is marked by exploiting others for personal gain. Raina’s transformation from a girl bent on revenge to a woman fighting for her people reflects this journey from moral certainty to moral discernment. Through her arc, the novel explores what it means to do good and what it costs to become good in a world fraught with pain, power, and ambiguity.
