I don't know if this has been the subject of discussion here before, but I suppose you do know about the Stanford Prison Experiment and the Milgram Experiment. Do you have any thoughts in regards to the test subjects behaviours? How do you feel when someone tells you that your personality and nature has a darker side, that is prone to come out under the right circumstances? And by darker, I mean a sadistic, hateful and psychotic side. Do you think you would be able to control yourself, if you had taken part in one on the above experiments, either as a prison guard, or as a prisoner, or as a teacher? Does the fact that a personality can so easily be twisted frighten you? Describe your thoughts and describe your reaction to stress in general. If you have never heard of the experiments before, here are the links in wikipedia. They are extremely interesting to read. Stanford Prison Experiment http://en.wikipedia.org/wiki/Stanford_prison_experiment Milgram Experiment http://en.wikipedia.org/wiki/Milgram_experiment There was also a German movie, Das Experiment, which was depicting some facts that took place during the Stanford experiment. I recommend it, but it's not for the faint-hearted.
