The exception to the above may be my demon theory but even if there are things like that, we still know right from wrong - at least we do within our own terms of undersanding/learning. The difficulty there would be listening to the right. I'm not promoting Christianity here or suggesting it is any more valid that any other belief system but the simple "Love thy neigbour" idea can go a long way regardless of faith. It is perhaps one we will all need to apply soon...
