Lawrence Kohlberg's model of ethics in 6 stages

The most powerful idea/concept that I used while watching the "Roll Red Roll: Steubenville" documentary was Lawrence Kohlberg’s model which focuses on the 6 stages of increasing depth of reasoning when contemplating best ethical practices. 
In short, Lawrence Kohlberg’s model theorizes that the lowest stage of ethics is when individuals make moral decisions on the basis of what is best for themselves without regard for the needs or feelings of others. These people only obey rules only if established by more powerful individuals, and disobey when they can do so without being caught. Throughout the film, I observed many individuals, besides the perpetrators, who decided to keep vital information to themselves until pressured by a more powerful force, such as, the police. 
On the other end of the spectrum, there lay the universal ethical principle where individuals adhere to a small number of abstract, universal principles that transcend specific concrete rules. These people answer to an inner conscience and may break rules that violate their own ethical principles.
I also considered Carol Gilligan’s orthogonal axis of ethical care. Her axis of ethical care states that an obligation of care rests on the understanding of relationships as a response to another in terms of their special needs. It focuses on the moral value of being empathetic toward those dearly beloved persons with whom we have special and valuable relationships and the moral importance of responding to such persons as unique individuals with characteristics that require custom-crafted responses to them that we do not normally extend to others. 
I observed how each individual in the film responded to the situation ethically and within their best ability, and then determined the differences between being positively moral or ethical, or negatively moral or ethical.
