All factions are based on real-life people do when calamity hits their hometowns. Some people stay and fight for what they believe in and from the opposing view, sometimes are referred to as being radicals or extremists. Maybe even terrorists. And vice versa when it comes to the other side. Some people would stay and put up with it, and rebuild when everything is over. In this case, a brave notion, but some would call these people being stubborn. And some people leave their home because it's too dangerous and become refugees, finding safe haven for their loved ones. Fact is, there are plenty of refugees in the world. Even now, people from Syria have fled their home to avoid the worst for their families. The lore behind this is set relatively close to reality. This is what happens during war. Would you look down on anyone for choosing any of the above forementioned choices? I wouldn't. Every has their own situations and it's their choice to make. And yes, this is a video game, but the options are the same. It may be more of a choice for what color you want to wear, but the lore is still based on the history of real life war situations. My point is, all options are viable, both in shaders and lore.
