He'd have been better prepared for trauma if he had watched Rambo...R
But Rambo would have no trauma. Nor would any other Hollyweird Hero.
My guess is he watched too much bullshit and that's why he was so careless with a gun.
When I turned 12 I was given a 22 and got a $10/year gun range membership with safety course.
Before then I played with toy guns a lot in games like war and cops and robbers, man from Uncle, etc.
After that I didn't point toy guns or unloaded guns at people. Can't be pretend when you have the real, that can lead to mistakes.
As far as I can tell, lack of responsibility makes for empty heads.
