The End of an Era
Matt Murdock has more in common with Steve Rogers than most fans are willing to consider. Both have a strong devotion to peace and justice and are equally talented fighters and leaders, but there's more.
In the Marvel Cinematic Universe, it took the Star-Spangled Man three movies and several crossovers to finally complete his transformation into Captain America, the hero who fights for truth and justice, even if it means engaging the American government -- the very same people he swore to serve back in Captain America: The First Avenger.
Daredevil had the same character arc on Netflix. He began his legal and extralegal career wide-eyed and idealistic, but was eventually broken by the circumstances of his time and the various misfortunes he seemed fated to suffer. In Season 2, he began to doubt and criticize the same legal system he swore to uphold shortly after graduating from Columbia University, even going so far as to operate completely outside of the law in Season 3. In The Defenders, he was disillusioned by the death of Elektra Natchios and his failure to come to terms with Frank Castle's way of fighting crime, and he began the show having retired from vigilantism.
In the final scenes of Daredevil's last season, Murdock spoke before Father Lantom's mourners about how the old priest raised him, teaching him how to become "a true man without fear." When Matt screamed in Wilson Fisk's bloodied face that "you don't get to destroy who I am," while strongly resisting the urge to snap his neck, we knew then and there that Daredevil, after three seasons and one crossover, finally had his hero-defining moment.
Daredevil himself implied his own complicated character trajectory, and finally his growth, in the same way that Captain America: Civil War fully defined and realized Rogers' identity, culminating in him telling Iron Man he wouldn't stay down, barking, "I can do this all day." Daredevil had the chance to complete his hero's journey in The Defenders, but failed when he wouldn't relieve himself of his traumas and obsessions. The good news is he had his second chance in Season 3 of Daredevil, where he finally learned to let go.
Daredevil has long been painted as a street-level vigilante, incapable of handling supernatural threats or collaborating exclusively with anyone else, but Matt Murdock is as much a superhero as any other, on par with even with the likes of Steve Rogers. Both were augmented by chemical means and are practically more skilled than any other fighter in the Marvel Universe. If little Steve could become an Avenger, there's no reason to think visually-impaired Matty couldn't reach the same heights.
Marvel's Daredevil is currently streaming on Netflix.
