First off, I'll say I've personally always been more sympathetic to the helghast in this series. I used to hate the ISA, always wanting to see the main characters die or something (I think we can all at least find common grounds about this with Rico). But, the more I have read the backstory and the more I've played the games, I've lost alot of my hatred to them. Rather, my hatred has transferred to their older brother, the UCN. Throughout the entire series, the UCN has maintained an iron vicegrip on the colonies, threatening practical armageddon to anyone who so much as considers the idea of being independent. The First Extrasolar War shows their intentions to anyone who dares to question them, yet the ISA armies unquestioningly protect the UCN with even more determination and vigor than they defended their home planet. I've never understood why the ISA hold such unwavering loyalty to a group that essentially is extorting them at gunpoint, maybe they just have a really good propaganda department. I'm personally hoping that the UCN ends up being shown as the primary antagonists of the series at one point or another, maybe starting a three way war between ISA, UCN and helghast. I dunno, it was just on my mind and I felt like typing it.
