I think Anakin was perfectly justified in wiping out the entire camp after what happened to his mother. You could argue that the women and children didn't have anything to do with Shmi's capture and death, but they were there while she was being tortured for a month, remember. They knew about it, and they did nothing. If they had any compassion for humans, one of them would have released her. But they didn't, and paid the price. They were animals, and he killed them like animals. Good job.
