Think thats the whole point of being a Soldier, u do some of the worst things ever to protect the rich motherfuckers, but they say to u its not to protect them, its for some abstract concept like freedom, fatherland, justice, democracy, etc, its a kind of brainwash.
Just look at US Army, they kill people all over the world just because some rich old guys in D.C said they shoud do it, yet they think they are the good guys.
