If death is final, a rational agent can be expected to value his life highlyand be reluctant to risk it. This makes the world a safer place, just as a planeis safer if its hijacker wants to survive. At the other extreme, if asignificant number of people convince themselves, or are convinced by theirpriests, that a martyr's death is equivalent to pressing the hyperspace buttonand zooming through a wormhole to another universe, it can make the world a verydangerous place. Especially if they also believe that that other universe is aparadisical escape from the tribulations of the real world. Top it off withsincerely believed, if ludicrous and degrading to women, sexual promises, and isit any wonder that naive and frustrated young men are clamouring to be selectedfor suicide missions?
