If nothing matters then it does not matter that nothing matters
It seems to me people who often take on the 'heaviest' responsibilities, or who are in positions of enormous responsibilty, paraoxically are those who are most comfortable with the notion of limited responsibility. Thus heads of state may send their armies into justifiable or unjustifiable conflicts, but usually don't take personal responsibility for the 10, 100 or 1 million deaths of their "own" soldiers - and never mind those of the enemy. If it were not so how could they continue to function. Indeed some , like Menachem Begin, could not, perhaps becuase he did not really possess this ability to shrug off responsibility. He seemed overwhelmed by the weight of the Israeli fatalities in the First Lebanese War, and became a recluse in the years immediately proceeding his death.
