It’s all about pushing you over the edge.
If you(general usage of you) can’t handle someone yelling at you and trying to make you lose it in a somewhat safe environment, you’re probably not going to do well when people who hate you are trying to kill you in the middle of a battlefield.
Folks don’t realize, the abuse is meant to mentally prepare you for folks trying to kill you.
I understand that... but what if you already know you don't belong there and had no choice i the matter? What is gained by abusing a human being like that... for the mere sake of abusing them? There is nothing glorious or attractive about it to me.
I kept my sense of humor, willingly put up the shit and realized “I’m up against people from NYC, Chicago, Butte Montana, and Bumfuck Egypt.” I Graduated with honors, listened to kids crying “Mommma, Momma.” all night long. Grabbed kids by the nape of their neck to TRY to get them to finish a run on the track. All the time I inwardly laughed. I’m damned proud I got out of basic. I also gave the same attitude to any other training I got before going to VN, (always with an honor certificate). I actually laughed at a lot of the training because I ALWAYS had in my mind “How many guys went through this same thing (training) and didn’t get killed?” It was the greatest ego booster I EVER had, because I showed MYSELF “I’m as good (or better) than ANY man I ever met.” There may be better, but not the ones I served with.
