Eventually you run out of clones. Death is temporary only so long as you have a new vessel to move into. Moreover, the experience of death must still present some level of terror. There is always the uncertainty of being GÇ£resurrectedGÇ¥ so to speak as well as the attendant unpleasantness of dying violently. IGÇÖve never died, but I have been stabbed and someone attempted to strangle me while I was sleeping and I would prefer not to relive either experience if at all possible. Moreover, the narrative arc requires consequences of some kind and one of these consequences must be the specter of death. To dismiss this fictional account of war based on a technicality is lazy criticism.
