So a 14 year old murders someone. Let them go because "Science" says that the kid isn't rational? I guess it isn't his fault huh? Yeah, screw it. Don't let them take responsibility for any of their actions. I get what you are saying, but because kids are less rational does not excuse their actions. They still have choice, even if they are more inclined to do something stupid, they don't have to. It is them as an individual who does what they do, because they chose to do so, and because of that they deserve complete responsibility for their idiotic actions.
