I like this one because it for once shows that the ones who do the actual killing don’t take it lightly. They probably know that they will be heavily traumatised after doing such a “job”.

late edit: Also interesting to see where the dehumanising starts. The directors in the bunker have it only on a screen and thus seem so remote that it appears more like a game, making them cheer the same way as if it would be a football match (notice again the contrasting behaviour of the guy flying the surveillance camera). – It’s much the same thing that happens in this very forum here. A good case study into human social dynamics.
