I answered your question with a question because I did not know what you really expected anyone to say here. Did you expect anybody to say no, we don't blame him for torturing and killing the students? I thought you were gonna say something different yourself.
As for blaming the people, I disagree with you. People were there in the streets, getting killed and tortured for all the injustice that you just mentioned. Who were the ones who stood by? You and I who were sitting in our comfortable homes in Europe/Canada, watching the people getting killed have little right to judge those people who were actually in the streets, fighting!
i have every right to have an opinion. and no people did not support the students. if they had IR would have been under a different type of government by now (or maybe in civil war ...) cannot guess.
this whole theory of sitting comfortably in our home in Europe/Canada is bullshit. please refrain from bringing it up simply because there are hard lives everywhere and there are easy peasy lifestyles all over and nowhere MORE than IR.
I have had conversations with several people who took active parts in green movement demonstrations in Tehran, Shiraz and tabriz, (two of them sit across from my cubicle at work and i hired one when i was a manager a few years ago. and they all told about their experiences but one thing they all concurred on was that the demonstrators were mostly students and spies of bassidj and ordinary people (civil servants, businessmen, doctors, dentists, toilet cleaners and millions of unemployed) did not support them for the simple reason of being scared of bassidj and sepah units that were armed to the teeth.
they took part in demos in shahyad square, sabalaan, amir aabaad for a few months nearly on weekly basis.
There is a reason i am sitting on my 'comfortable' place in Canada. 30 years ago your emaam khomeini said that people like my family are not welcome to stay in IR anymore and if we value our lives we have to leave. Unfortunately for me i was not old enough to stay and at least get myself to a place to hit back at the people who wanted me out otherwise i would have.
maybe you had a 'normal' yes it is called normal not easy life with the support of your parents or family but not all of us have had easy lives outside IR. Some of us have cleaned toilets, delivered pizzas, spent many nights with less than a pound in our pockets.
don't go summerizing everybody's life with your own.
