There's really no such thing as the agony of dying. I'm quite sure that pain is shut off at the moment of death. You see something happens when the body knows it's about to go. Peptide hormones are released by cells in the hypothalamus and pituitary gland. Endorphins. They attach themselves to the cells responsible for feeling pain.
It was by design that we mostly used pictures that you could not necessarily see what was going on and that didn't really focus in on the band but instead focused in on a theme.
