In a few branches where the gun/bomb/whatever fires/explodes/whatever, he still survives, though probably horribly injured/mutilated - something he will have to live with for an indefinite future. Obviously the ratio of the former to the latter is huge, probably astronomically huge, but there is still a finite "chance" (or rather certainty) of ending up as the injured party. So playing quantum roulette effectively means I am condemning some of my future selves to a nasty fate.
