One of the worst things about evil is that all too often, those that are the principle actors of evil, believe that they are doing a good thing with the best of intentions.
Take for example the teachers that had their students send letters to the Israeli Ambassador to Spain in Madid that asked "Mr. Ambassador, how many Palestinians did you murder today?"

This is a deep evil that has been done to these children. It invests them personally in the hatred by making them participants.
Everyone wants to believe that they are good. They also want to believe that the people that they love and respect are good. Now that these children have participated in this, they will have to confront their participation in something that is not good. A thing that they have been persuaded to participate in by people that they love, trust and respect.
The personal struggle that they will have to confront will be too much for many if not most of them. "How" they will reason "can people that I trust and respect goad me into evil? If they are good and deserving of my respect and my love, then what they have made me do must not be evil."
The teachers and others involved in this project surely believed that what they were doing was right and good.
What these teachers have done was a deep evil.
Who can repair the damage done to these children?
