Oh, definitely. I'm hoping that that'll get reflected in Sera's storyline, actually. She joined up because she was angry about the way Earth treats Mars as well as personal issues as a result of it, but now that war's broken out, is wondering if they really need to go this far. She's still emotional about the events that led to her decision, but how many more people have to die? How many deaths can you justify? What kind of reparations are acceptable, and when does it get punitive?
I'm a fan of Zeon, but I think that a lot of their actions weren't justified, even in the name of independence. A lot of the soldiers for Zeon were good people, but conflicts like this are bigger than any one person, bigger than they can see from their perspective. It'll be interesting to see how this plays out in Sierra Ops.
