If you want to prevent things like this from happening in the future, if you want to learn about the human mind and what makes us tick (and what makes us do terrible things), then why should they all be executed? There is a lot to learn here: group think, youth thought processes, adult/youth interactions, etc., etc. This is a case for our time. We can learn much about human psychology, and it's all right here.
