Well, we don't know enough about this case to really judge it. But my key take away is NOT that this kid is a future murderer, but rather the opposite, that internet harassment is something very different than real harassment, something normal people can get into, somewhere where it's too easy to disconnect emotionally from the target and the suffering of the target. The kid may not have been able to visualize the suffering that he caused, getting de-sensitized to the words and images used in the harassment (you don't need to stay long in 4chan for that to happen). Of course, it doesn't make it more ok, it just means we shouldn't use the same ruler to measure internet harassment as real harassment.
