I still think you're missing the important aspect by this emphasis on the so-called "shadow side". What the experiments made clear was not that people went as far as they did through some dark, hidden potential for evil, sadism, etc., but that it was far more a matter of compliance, obedience, deference to authority, etc. Things which do have their positive sides in moderate doses in an interdependent, complex society - a lot of teachers' lives are made hell these days due to the lack of such things.

Most people went on very unwillingly and were in clear discomfort, this has nothing to do with your angry violence in a game. Yes, we are extremely flexible creatures and we are capable of anger and violence, necessary for survival in some extreme situations. Stressful situations can lead to unprovoked violence, as we know from experience such as yours as well as experiments on rats.

But it's as well to make relevant distinctions between compliance, deference to authority and angry violence and personally I don't find the need to put the latter into a "shadow" category; it's just another human capacity, sometimes necessary and justified - like compliance.

Maybe it's because I'm a Londoner - that I moved to Nice.
