@Gekritzel: It seems like they weren't people to begin with - none of them show typical anime "oh my god I'm turning into a monster" signs. Mostly they're just like, "Oh, okay, I'm a Zerivre. Hehehe."
I find it strange out of all those 10,000 civilans that died they don't even show the slightest care or even the chance that they might be able to return them to normal. What are they fighting for?
