Over time you are trained to cut yourself off from yourself - suppress anything you feel, think or want in service to the organization. If you are born-in, you don't even know you've done it and to what extent until you leave (if you ever do).
It is sort of like the illustration of the fish not seeing the water it swims in...or even the experience of a lobster in a pot of water that slowly warms to a boil....the level of control exerted is undetectable if you are convinced it is for a higher good.
And, most people want to be and do good. So that was the motivation for enduring things that were mind-numbing and sucked the life out of us.
