Basically, humans being humans; I'm not surprised. The worst part is that a lot of idiots have the nerve to take offense with phrases like “humans are a plague.” And before someone spits the “it's just a manga” fallacy at me, let's remember that, in real life, humans skin various animals alive just because their skin “looks nice” or kill them to extract something from them (I will not include eating them because that is a natural process). Unfortunately this manga reminded me of this fact. That's why I don't like reading this kind of shit; they bring out my misanthropic side.
