Responsibility is not something that can be assigned or delegated.
Unfortunately, in the movie we watched, Hunger Games: Mockingjay, Part 1, we witnessed Katniss Everdeen being assigned responsibility for this entire movement, she was given a choice, but the pressure was on her, especially with public perception. It is not always true that responsibility cannot be assigned or delegated, because occasionally, there may be a witness or victim that so many people rally behind, that they begin a movement. Such as the Stanford rape victim, although unnamed, she has ignited a movement across the country for reforms within the criminal justice system, and she's indirectly responsible. Her letter sparked emotions in people and that sparked action with their unnamed leader being her. She does not necessarily have to be actively involved, but she set this major news story in motion by being courageous enough to share her story.
