Those who actually set out to see the fall of a city or those who choose to go to a front line, are obviously asking themselves to what extent they are cowards. But the tests they set themselves / there is a dead body, can you bear to look at it? / are nothing in comparison with the tests that are sprung on them. It is not the obvious tests that matter (do you go to pieces in a mortar attack?) but the unexpected ones (here is a man on the run, seeking your help / can you face him honestly?).
