I believe that the evil side was well portrayed. Bad things happen sometimes because of the cowardice that some people harbor as they chose to convince themselves of being "innocent" bystanders. If only Hiroki - or what's-his-name - has kept quiet and let the girl escape. If only he had gathered up the courage to say something, she wouldn't have had to endure what she has gone through. In my opinion, he is more guilty than the other members of the gang because his selfish and pitiful cowardice was a crucial fact in triggering and prolonging her sufferance ; and they all got off the hook easily. Justice was far from being served.
