"Just because you hate Spacians, you go on a rampage for no reason and kill people. If all you do is cause suffering, no one will ever listen to Earthians' voices. What you're doing is wrong!" ~Nika
Right, because militaristic and economic disparity for X number of years on a planetary scale that essentially means your rights and voices are null (because, y'know, Spacians already haven't been listening to you) is totally not a reason, even if Nika's comment was targeted only at Norea in that scene.
That sentence must be translated wrong because "Just because you hate Spacians, you go on a rampage" means that she thinks the reason is hating spacians.
Also very hard to that Nika and Norea conversation about war and politics seriously when Norea is animated to look like a mentally-stable 12-year-old. (Suletta looks like she's 14 and Norea is supposed to be a few years younger)
