There's too much to say about my country, and it's irrelevant to this manga anyway so I won't elaborate further.
Suffice to say, the world has become a very bitter place, and personally I find the dismissive or even deriding attitude of many to this issue both worrying and disturbing.
This is also why I read this manga for Serizawa's side of the story. Someone had to deal with such bitterness for so long they snapped, and now they'll spread as much misery as possible before they self destruct. And even then, the ones who, with their actions, turned this person into a ticking time bomb either fail to understand their part in it, or refuse to acknowledge it.
Mind you, I'm not justifying Serizawa's actions (I said before they are inexcusable). I am, however, at least lending an ear.
