The optimistic young revolutionary Nemik dying because someone forgot to secure a load was soul crushing but so real. They purposefully chose not to let him die in battle and become a martyr because whether or not we like to admit it most of the people that die in that sort of fight don't get to be martyrs. He won't be remembered in the annals of the revolution for many years and if he ever is it will be for the unfortunate accident, not some heroic sacrifice to save his comrades.

Even extras in many of the other Star Wars films and shows get a more glorious death lol. The unnamed rebels at the beginning of A New Hope at least die with blasters in their hands fighting a dark lord but there's none of that in Andor.
