Well, before this turns into a cat fight.......
Here are a few things to consider......
Displaying components or behaviours of a personality type, does not make you that type. IE, displaying a learned personality trait associated with a sociopath does not make you a sociopath.
Being 'Like" does not translate into "Are", and it's worth remembering that.
Secondly, we often accuse people who haven't been through the domestic traumas that we have, of not truly understanding why we are affected the way we are. We should be very careful not to do what we hate the most to people who, like us, have PTSD, but have obtained it in an entirely different manner.
Finally, combat veterans are/were humans before they received training that would allow them to operate the most efficiently with least damage to themselves. 'Sociopathic' thought processes and behavior that is instilled into these people is, for the most part, broad spectrum and designed with minimizing mental and physical injury, whilst maximizing the effects on the enemy.
Any 'interactions' between personality and behaviors taught is purely individual, and therefore the term 'sociopath' cannot be applied to an industry specific area, but rather to specific personalities which trend towards sociopath behavior with or without the assistance of reinforcing training.
Do I make any sense, or have I tied myself into a granny knot?
