Different cultures have set up different mental constructs to help them better understand the world and make decisions. The sad truth is that society would take forever to get anything done if we were able to see a situation from all perspectives. And when we would look at all these perspectives we would realize that no one person is to blame for any event. Rather we would have to come to terms with the reality that we can only blame situations and not individuals. This of course makes punishment incredibly more complicated. Humans like having a single entity to blame for their problems.
