Yes, there are some who have a conscience. But no matter what the military wants to state, they do try to brainwash recruits in basic training. They call it "un-fucking your mind" in there. They break who they can break, and put those who they see are already strong in leadership positions.
In the Marines, at least when I was there, they were already starting the brainwashing of Marines against it`s own civilians. Honest to God! They call them "rat nasty", and get you to start looking at them that way. They even pointed fun at the civilians who came on base for graduations, kind of like proving the point I guess. I`ll admit, that was the only front they had me on for awhile until I saw what was really going on.
So while there are people such as myself, who can see the truth, and know the different between right and wrong, there are many, and I mean many, who have been brain-fucked into their beliefs.
