Oh my God I think I know why they chose the name "Scapegoats"
So in abusive parenting dynamics of two or more children, there is almost ALWAYS a "Golden Child"- the child that gets all the praise, can do no wrong, gets the better toys and clothes, the better treatment in general; then you have the "Scapegoat"- the child that is the one that gets all the blame for whatever goes wrong in the home, usually gets crappy hand-me-downs at best, and is treated like a burdensome shame to the family.
Y'all- the scapegoats are former reagents, it's all but confirmed in their voice lines "There's no freedom, it's a lie. I'm the ghost of Christmas fucking future you ignorant dummies" and "Why would they want to hurt me? I'm just like them. I *was* them. Can't they fuckin' see that?".
It's also incredibly common in these dynamics for the abusive parent to pit the children against each other, usually with very Machiavellian methods; there we have Easterman, who touts himself as a "father figure" to reagents, giving us praise if we do well in trials, giving us "guidance". Meanwhile dehumanizing and using the scapegoats to further our, and therefore in the bigger picture *his* interests, obviously at the massive, ultimate expense of the scapegoats.
The current reagents are the Golden Childen, and well, the Scapegoats are self explanatory atp.
Idk why I didn't realize it at first but imo it tracks and it's a BRILLIANT name choice that seems SO simple at first, and can honestly be hard to catch if you are unaware of, or haven't been a part of dynamics like this. Way to go Red Barrels.
