Matt is always moving forward. He doesn't look back. That's not to say he doesn't grieve or mourn or feel regret. But he understands he can't take back what has happened, what he did, or change the past. He works, he attains, he moves on. He doesn't amble about feeling sorry for himself to the point where it interferes with his work; he stays on task, stays sharp, and realizes there's more people out there that need saving. Sometimes, Batman gets a lot of gyp because he can't get over the loss of his parents. Sometimes Spider-Man is too busy crying about Mary Jane to do anything effective. And while Daredevil has those exact same elements in his stories, they're by no means crippling. On the contrary, runs like Yellow and Father don't keep Daredevil in the past; they push him forward, with development for all the characters, including the ones that have already died and don't even make material returns to life. Daredevil will forever miss those he's lost, and with an incredibly heavy heart. But he's also a superhero who forgives himself for his failures, which is a milestone in the comic book world.
