The devastating death of Foggy Nelson in Daredevil: Born Again has resonated deeply with audiences, particularly in relation to the character of the Punisher. Frank Castle’s prior confrontation with his own version of Foggy in the Marvel Cinematic Universe (MCU) sheds light on his reaction. Having appeared in two seasons of his dedicated series, the Punisher makes a notable return as a supporting character in Daredevil: Born Again. Although he shares only a single scene with Matt Murdock, it is a powerful exchange that reinvigorates the Punisher’s moral framework.
Jon Bernthal’s portrayal of Castle is a striking reminder of how their differing perceptions of justice stem from shared motives, each rooted in complicated experiences. During their tense discussion in episode 4, Castle presents a compelling argument against Murdock’s philosophy of cautious restraint when dealing with the vilest offenders in Hell’s Kitchen. This perspective is undoubtedly influenced by Castle’s harrowing past.

The Brotherhood of Frank Castle and Billy Russo


Before their ultimate falling out, Billy Russo was not just a friend but a brother-in-arms to Frank Castle. Their camaraderie was built upon shared trauma, reminiscent of the unyielding bond between Foggy Nelson and Matt Murdock. While Russo eventually transforms into the villain known as Jigsaw, he serves as a crucial reminder of Castle’s previous life before taking on the Punisher mantle.
Both Russo and Foggy share the profound knowledge of revealing the true identities of their heroic counterparts. Russo exemplifies the potential darkness within Castle, while Foggy represents the ideal of justice and faith in the legal system that Murdock strives to uphold.

Frank Castle’s Merciful End for Jigsaw


In The Punisher, Billy Russo’s descent into villainy comes after his military service alongside Frank Castle. His shift leads him into collusion with Agent Orange, resulting in the tragic slaying of Castle’s family—a pivotal moment that drives Frank into his vengeful crusade. In spite of his goals of vengeance, Castle ultimately opts for a mercy killing for Russo, believing it to be a release from his friend’s debilitating transformation.
When Castle finally confronts Russo, he chooses not to execute retribution but to end the suffering that his former ally has been subjected to, which cements the complexity of their broken relationship.

Frank Castle’s arc and the heart-wrenching choice to end Russo’s life profoundly influence how he responds to Foggy’s death. His heated debate with Matt reflects an authentic empathy, understanding the weight of loss Matt faces due to Bullseye’s actions. Punisher’s challenge to Matt—that simply imprisoning Bullseye doesn’t suffice—is rooted in his own harrowing past decision regarding Russo.
In this context, Castle’s justification for taking Bullseye’s life resonates more deeply, as he recalls that killing Jigsaw was essentially an act of mercy towards the friend he had lost to darker forces. This contrast underscores Castle’s evolution into one of the most nuanced and tragic heroes within the MCU, showcasing his layered motivations and struggles with morality.
