dunno if you get it yet but they all are there for a wrong reason IMO, and
You gotta have characters like the guard to abuse them, right?
thats exactly the reason why they look like that, to show tha tthere are worse ppl in the world that those tha tare already behind bars, if you watched Higurashi second season where Miyo's childhood is revealed (the orphanage) it's ppl like that that should be behind bars, or worse, l'd give them death penalty, seriously, l can give crap about abusing the adults, but abusing children is simply the worst crime a human can do (of curse anything worse that simple abuse is worth 10K deaths)
l don't understand why our species enjoy abusing ppl like that, l think us humans are the sickest creatures in the whole universe.
all six of them are because they stood up and defended someone in one way or another, ofcurse after the war courts took a lot quicker way to quickly deal with more dire problems, but it's all fault of the system, personally l would give all of them a medal of honour.
