The consonance of the 'priest preparing' is seen as violent as plosive sounds are used to depict to us how these people died. As he develops these photographs, religious imagery is used ironically to compare him to god but he is actually looking at death/ pain. The 'Mass' could also be used for the reader to question if there is a god, as who would allow for mass catastrophic events to occur, 'Mass' could be referring to mass death. Duffy was a laxed catholic so she is entrenched with religious language. Duffy begins to list conflicts, which get bigger and bigger in affects.

Lastly the abundance of full stops could be reflecting bullets as people die or the snapshot of the camera as the photographer takes photos.
