Waaa

Read this all in one night I'm so mad its not completed... it's hard to say at the moment with so little info and that mainly came from the military's pov... but looks like both the military and the garden of eden are awful organisations greedy for power. In apocalyptic settings (or just any setting..) the military/government is always the villain for various and obvious reason and I'm convinced its same here with all the things they hide and discard and how they treat both civilians and lower ranks. The opposite, one of many, is the garden of eden organisation/cult/religion but even them don't seem the best to lead the people...
Also I'm not sure if people in the comments got it but Major Kwak does not want dr. Seok to get into trouble and finish in interrogation room again since hes always under surveillance, he said it in such a way to discourage him, though of course it didn't really work. Also I firmly believe he is not on either the military or the garden of eden's side.
