Abandoning Pink's specific tale for perhaps the first time, the album concludes with "Outside the Wall," a sort of generalized epilogue addressing the main theme of "the Wall" (at least for Roger Waters) rather than the specific story of the protagonist. Thematically, this last song is very much akin to the revelatory "Bring the Boys Back Home," which Waters felt to be the centerpiece of the album. Like the earlier song, "Outside the Wall" is about the community that comprises this world, and the personal connections that serve as the foundation for all of life. Just as "Bring the Boys Back Home" is a reminder within the story to not let anything become so important as to outweigh one's humanity, "Outside the Wall" depicts this same view from a different perspective, from those who "walk up and down outside the wall" trying to reconnect with the loved ones trapped within. Some walk outside the wall "all alone," like Pink's wife who tried to break through her husband's isolating barriers, only to "stagger and fall" as a result of Pink's continual lack of communication, turning to another man for solace and affection. Others are "gathered together in bands," where "band" could either stand for a group of people or, in another self-reflexive statement, the actual "bleeding hearts and artists" like Pink Floyd themselves who attempt to evoke change through their art. In a way, that's what "the Wall" really is: the band "banging [their] heart[s]" against the personal and social walls that stand throughout the world.

And though the cycle begins anew as the song ends, with "Isn't this where…" signaling the end of the album, there is still hope that the cycle can be broken. For no matter how many walls are erected, there will always be people "out there" that try to break them down. It's what Waters did after recognizing his own wall. He and his bandmates conceived and recorded an illuminating testament concerning the decay of individuality through isolation and the hopeful rise of the individual as a result the common bond of humanity. If Pink's story tells us anything, it's that though the cycle of violence and oppression repeats itself, it doesn't have to. All it takes to break that chain is a change in perspective, a realization that through it all, one is not alone.

The movie sequence for "Outside the Wall" really leans towards this hopeful message of terminating one such cycle of violence. The scene fades from white onto the day after a riot (presumably the one pictured in snippets throughout the movie) as various people go about cleaning up the debris. The camera pans down to show young kids gathering bricks and other wreckage into baskets and toy dump trucks. While some argue that the kids are merely continuing the cycle, symbolically gathering the bricks for their own psychological walls, I think the final shot conveys an overall sense of optimism. As the children gather the debris, one child finds a Molotov cocktail, or Petrol Bomb as Waters calls it, recoils at the smell of the wick, and pours the petrol from the bottle. As Waters says on the DVD commentary, the child "defuses it" and, along with his other child friends, begins to bring order to the chaos of the previous generation (the ones who started the riot). Waters continues by saying that the child "decides to build rather than destroy," breaking the cycle of violence and oppression in this one instance. It's also interesting to note the reworked style of the song for the movie, featuring an orchestra and vocals similar to the music from "When the Tigers Broke Free." Though the movie begins with war, turmoil, and the creation of one man's wall, it ends with peace, the destruction of that very same wall, and the hope that the follies of the past will corrected for the progress of generations to come.
