I wouldn't blame them for it. Stanley Kubrick's Paths of Glory seems like a good illustration of the potential backlash the participants were facing. Later on the Nazis had a law called Wehrkraftzersetzung, that among other things was meant to punish soldiers who (vocally) doubted victory. Probably in part because decades earlier the Great War was cut short by a naval mutiny, or rather something Hitler types would end up feeling very Dolchstoßlegende about. The kind of nincompoops who keep on gambling trying to cover their ever-increasing loses. But next spring they're going to win. This time for sure!

There's certainly some romanticism to that whole notion of a heroic death, when it's more or less just a glorified pawn sacrifice. Meanwhile pawns actually refusing to strike eachother? Now that's very bad news indeed. The King told me you should be more like that brave cowboy from Dr. Strangelove, who rode that bomb into target and ushered in the apocalypse while waving his 10-gallon hat. Be less like Stanislav Petrov, who refused to press the red button back in 1983.
