The introduction of Fabiola Iglesias reinforces this. She is a mirror to Revy—young, skilled, and violent—but she still holds onto a sense of human dignity. Her final confrontation with Rock, where she spits on his philosophy, highlights the OVA’s ultimate thesis: in a world of monsters, the most dangerous person is the one who treats human lives like a game of chess. Conclusion: No Winners in Roanapur
Roberta’s Blood Trail concludes with a hollow victory. While the physical cycle of violence briefly pauses, the psychological damage is permanent. The OVA cements Black Lagoon as a tragedy.

The OVA uses Roberta to critique the concept of the "righteous soldier." As she hunts the American Special Forces unit responsible for the hit, she isn't just killing enemies; she is hallucinating the ghosts of her past victims. Her journey is a visceral representation of PTSD and the cyclical nature of political violence in Latin America. She becomes a force of nature that doesn't distinguish between the guilty and the innocent, effectively becoming the very "monster" she once fought against as a revolutionary.
