@SotiCoto Ok... friend you really need to relax, i think you are letting your anger or dislike of Gouhin cloud your view a little too much, if you don't like the chapter, ok, but i think you got the wrong idea about her decision, she didn't do that for society... she did it for herself, she wants to accept the fact that she killed someone, someone innocent, he was just a random rabbit on the road, she doesn't want to be a justice warrior, she just wants to find inner peace and this was her decision.
And Gouhin isn't pushing some positivity agenda he is just telling her to be happy with herself, the smile thing was just a way of convey it in words, just that.
