Wow... all I can say about the attempt of humanization is that... there was an attempt. But it fail spectacularly in my eyes because the behavior he displayed was completely psychopathic and without reason. His acts completely lack enough motivation; If they showed him to be a fanatic of the organization and thus really believed that he was doing this for a greater good or If he for example was hesitating to kill the lil girl or smth cus he thought about his own, it would at least make a bit sense. He on the contrary was happy of to be slaughtering for the sake of slaughtering. You can’t just drop a bombshell at the end and expect us to feel bad for his death all of the sudden. So it failed to make me feel even a drop of sympathy for these people... all the characters really feel onesided.
