What was the purpose for all of this tragedy?

One of the most significant defining characteristics of revolutionary generation is being rebellious, or at least in my country-Iran- it was. Also one of the most significant defining of a succeeding revolution is that the majority of the people in a society rebel against the government’s authority, and children cannot be excluded from this majority. I remember one day during the revolution, we had some guests in our home. As usual their children were playing with each others. They were between the ages of four to seven. Something interesting drew my attention to their playing. It was the beginning of the game. They were introducing themselves to others. It was something like a referendum. One of them said that she wanted a proletarian government. Another one said he wanted liberalism and so on. I remember at that time I had a four years old brother. I loved to buy and read books for him. All of those books were trying to teach children to unite against the oppression. His common questions were about politics. For example, what “liberalism” meant, or why the Iraq attacked our country, or what “imperialism” meant and so on. The children witnessed the proceedings of the revolution and they were closely involved in these proceedings. This generation knew much more than the other children at the same age in other countries. A deep sense of social injustice was developed among the people especially children. They learned to resist to any injustice and violence, and after victory they saw the result of this resistance. They have earned this knowledge by practical experiences, not just by reading books or watching movies. Right after the revolution, all subjects and titles of books, movies and media were changed. However, the content of all was rebellious and resistant until achieving victory. Then children knew that they didn’t have to endure oppression. Marjan was not the only child who rebelled against the situation which she did not agree with. Iran witnessed a huge number of such rebels who were killed during and after the Islamic revolution.  Marjan and her family was one of the luckiest families who experienced a minimum of loss. They had money to send their beloved child to a safe place that nobody could kill her because of her opinion. Her family witnessed a lot of families who lost their children because of being executed or being killed in the war. An eight year imposed war which had no change in the borders, but left about half a million killed and wounded people who are still suffering the effect of chemical weapons, a war that just benefited the big weapons factories especially Americans factories, which could sell their weapons to both Iran and Iraq.
