Oh man I feel you hardcore, had to witness that, too, in training.  The douchers in the bunch I didn't feel so bad for, but like you said, there were so many young smart guys that hadn't gotten out much if at all from their small towns or ghettos that deserved better than this and were sucked in by the attention and were desperately lonely, so couldn't help but have my big-sister protective impulses kick in -- my little brother went through a couple of similar experiences around the same time, too, but dodged the baby-bullet with his ex so she only cost him the price of a good divorce attorney, but soon after that a girl he only dated a few weeks falsely accused him of being the baby daddy to her fetus -- kid was black and my bro is light-skinned Hispanic-Asian so anyhey, yeah, that's where I especially rage about this.
