I agree Bette blame is not a good word. I would say be responsible for their actions.
Clau - don't you know that ignorance is no excuse under the law? And I don't think it is in the VR either. Take two little boys raised the same way by the same parents. One becomes a doctor and one becomes a terrorist. Both are responsible for their choices. No excuses unless there is a physical/psychological defect that effects their decision space. Otherwise everyone would have an excuse for something.
I know ignorance is punished in PMR. A lot of people go to jail for just being ignorant. I understand your example, but it is easy when you have a clear parameter to determine what is right and what is wrong. Let's suppose the two little boys are raised in a small town and their parents teach them that it is good to defend their land. The parents were living in a land that wasn't theirs, but they thought it was theirs. The parents tell them that if they kill one of the "enemies of their land", they will go to heaven and have eternal life, and also their family will have eternal life. Their parents also tell them that they got visions from gods that it was right to kill to defend their land. One of the kids gets out of the house and falls down and gets injured very bad. A good guy from the ones claiming the land goes to try to help him and gets killed by the brother of the injured guy.
In the Moral Code part II thread, kroeran and you apparently have a different opinion on what's right and what's wrong regarding domestic animals. He might act feeling his doing the right thing, which may be the wrong thing for you. So, who's the one with no excuses?
