But blame... well it isn't actually blame, more so justifiable punishment... for a wrongful act can exist without any wrong doing. The depressing case is a soldier who is guarding a base. A child approached holding a bag. There could be food in there, and the child is wanting to give it to the soldier as thanks. Or there may be a bomb in there, and the child was tricked into delivering it to the soldier. In either case, the child has done no wrongdoing, but, assuming the child does not stop approaching when told to do so (as the child does not understand the language the guard is speaking in), the child will be shot if they get too close because of the danger they pose. Will the soldier shoot to kill? No. Can it kill the child? Yes. Granted, these days you probably will have options that allow you to stop the child with much less chance of killing them, but in the past, this was not an option.
The child is being punished, and justifiably so (this is not the say the child deserves to be punished, but the response, shooting the child, is justified in that it upholds the safety of the base the soldier is guarding), but has done no wrong.
