12 Year Old Boy Accused of Murder

In Colorado a 12 year old boy linked to the murder of his mother and father and severe wounds to his 2 younger siblings. This really makes me think more than just the obvious point that this is really messed up. How do people get this way? How do children learn this? This didn't use to happen, why is it happening now? Its really confusing that people that grow up with great parents and family and morals still turn out this way. I personally blame the media for kids knowing all this information about murder and killing. Think back to about 1970. There were only a few channels on TV, let alone shows and information about violence and murder. There were also no video games that involved murder or internet to influence kids. I'm not saying it never happened back then, but the violence and murder of parents by their own parents has gone up. I also just feel bad for the kid. He had his whole life in front of him and he already has a criminal record before he even finishes middle school. But the other part of me doesn't really care about that because people who act like this don't deserve to be out in the world with good people. Why should they be aloud interact with the good people in the world? Why should they have that privilege? Why should they have the same good things that we do when all they are is scum?
