I read somewhere else that Stone was only in Iraq for two or three months - sounds like a tour of duty cut short because of some problems, pre-existing or triggered.
So he had ‘problems’ before he even got there, sound like.
Maybe he personally thought he had ‘the right stuff’ to succeed, and decided to do or to say whatever was needed to go forward.
And I read he only served in the reserves. Whatever. Doesn’t sound to me like he saw much action to have contracted PTSD from his military service.
But I defer to those who have served. They would know more about this than I.
Anyone who slaughters his family has pre-existing issues, IMO. Feminism has created more monsters than any war ever could. Latch key kids have no guidance AND NO DISCIPLINE OF THE KIND ONLY A FATHER CAN GIVE.
