Frederick was one of the accused guards at the prison who was targeted with allegation of abuse of the inmates. His response to the allegations was that n no proper guidelines for operations were provided by the army to the guards and as a result the guards used their own techniques to contain the inmates.
This claim of the official shows how the guard assumed that his actions were moral and ethical under the circumstances where he and the prisoners were isolated from the norms of society, social constructs, and government authority as well as form anyone who could question the behavior of the guards to hold them responsible. This depicts that even the real life prisons where isolation from society and lack of guidance and accountability are present, the same results can be seen as were observed from the Stanford Prison Experiment.
The degradation of morality and changes in the cognition constructs for ethical decision making are not just present influenced by isolation in humans but also in animals.
