"All th adrenaline . . fueled death wish / You want to be the main character" . This is a song about a guy who wants to be a hero in the future, but he can't do it because he's not good at acting. He's got no choice, he says, but to "fight fire with fire" , which is why he wrote the song in the first place. The song's title comes from a quote from Shakespeare's play All's Well That Ends Well, which says, "All's well that ends well, begins with a good beginning." In this case, the beginning of the song is "All-th adrenaline--fueled death wish." It's all about the guy's desire to be "the hero." The song ends with the guy singing, "I need you, from now on / It'll be yours to change my own future." . The guy says he wants to sing this song because it's the end of the play, and the guy wants to hear the guy sing it.
