I'm willing to bet that if I go to my grandfather or any of his old war buddies that served and said "you didn't fight for your country or any of that bull****, right? just cause you wanted to kill people, right?" that they would take offense to that entire notion.
I'm willing to bet that if John Kerry said during the 2004 campaign that he didn't sign up "for love of country or any of that bull****" that all the people in this thread would still be talking about how big of an ass he had made of himself.
I understand everything you said, and alot of it makes sense, you have to ingrain some of this into people to get them to be as they need to be in order to deal with combat. It's not pretty, I'm sure, but required.
But, if someone tells me that he signed up just to blow **** up and kill people, and it had nothing to do with love of country, wanting to protect his fellow Americans, etc. it makes me start to wonder if what he/she did was really all that noble in the first place simply cause of motive, which I don't even like admitting just cause of the sound of it, but I'm just being honest.
But in the end, I still don't believe that blowing stuff up and killing people is anywhere near the top of the list for most people that sign up.
