There are innate character traits in each of us. Of course education/training/practice can move the needle a little up or down, but you can't really turn a very introvert person into a very extrovert one, for example.
Why not? I am extremely introverted, I became that way as a result of adapting to and learning from my life experience. Why can't I be taught through experience and having to adopt to uncomfortable situations, to become extremely extroverted?
There is a reason the military has a bootcamp,it's to break your personality so they can form a new personality that can take orders and lives without hesitation.
Being able to obey and follow discipline does not mean it changes your personality. Proof is, once men return to the civil life, nobody in their family says that they are a different person or something. The core personality remains.
Unless they have developed PTSD or something but that's trauma, not training.
The military made an ondemand killer out of them,how would civilians measure that change. The military doesn't make you a different person,nicer or meaner,the change they instill is simple -- your personality will obey lawful orders and work in a team.
