I'm watching it right now, although as mentioned its not exactly eye-opening since turning someone into a killer would take some serious conditioning, to see the actual process is definitely interesting.
I read a book a couple of years called "On Killing" which dealt with this issue, how the military uses Pavlonian and operant conditioning to overcome a person's instinctive aversion to killing. When you look at the rates of soldiers coming back with PTSS you can really get an idea of the cost of this type of conditioning (and obviously the effects of actual combat) has on a person.
Thanks for linking that!
