Few dare to rebel against authority individually (whether medical, political, police, scientist, teacher ...), even if staying in range means (openly and knowingly), pain, even kill a fellow. Experiments such as the documentary "The Game of Death" published in France in 2010 have proved it. The staging it reproduces the chilling Milgram experiment originally conducted in the United States in the 1960s to study the influence of authority on obedience.
Differentiate the group is too scary for many people. We are talking about collective unconsciousness of cowardice and selfishness. Amélie Nothomb is it, for cons, fully conscious and his novel is very brave. This is a plea for love of neighbor, courage, dignity, liberty, and honor. And he did that only takes one person at a time.
Stylistically, it is impeccable as usual, and more, right here was a real psychological intrigue and a super well-crafted script, which demonstrates not not the steps of the changeover from evil to good; even when evil seems to move openly, well makes its way in silence, by the force of the abovementioned values. Great art.
NB: I love the cartoon / caustic coverage paperback, where we see the rats flee in all bars and jump ship from the reality that is in distress. Animals foresee the danger and fled the inhuman world of humans, who are sawing off the branch on which they sit.
