In that same light, all of us programmers sold our souls for cash to make the Facebooks and Flocks and OpenAI's of the world. Don't throw stones when you live in a glass house.

While I'm some degree of a pacifist, it's tough to argue against the concept of a defense army, in the face of human nature. Defense in the larger sense also has to mean (preventative) intervention, for example world war 2 might have ended very differently unless the US joined.

I also recognize that the US has perverted this concept countless times since with blatant imperialistic motives, it does however still not break the concept of a just responsive military force.

TL;DR: They're not selling their souls if they (mistakenly) trust elected officials to work for the will of the people and only deploy for just causes.
