God created everyone, there are some children who were born into evil. What are they to do? I believe God has sympathy with them and if they do believe then may let them see the light one day. Fotl children in general i don't believe are evil at all, they may become so but they aren't when young. Those kids throwing stones, i don't think they've got it set in their heart that "oh yes, this is for israel, for our homeland," they are just influenced by everything thats around them, the media etc Thats what kids do. They may have thought it was a fun thing to do, the soldier didn't give a toss so they might as well grab their chance. Plus when theres a camera involved, you might as well make a show.
Violence is in excusable ftf unless for defence. This was not defence, just pointless attack. Although i wouldn't call it aggression.
