These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Designated Hero's: While it's pretty clear that none of the human protagonists are evil, many of them are friendly and helpful, to each other. Not only do humans take the Ymir from him his home in the first place. But there are many moments that show that while they talk about caring about the alien, they seem to be too fascinated by it's alien qualities to notice it's screaming in fear or pain more than half the time. In fact, when the alien finally is killed the leading couple seems more interested in making out in a restaurant than anything else. Only General McIntosh and Dr. Uhl seemed to truly understand (and care about) the tragedy that had just transpired.
