Sort of on topic/off topic about kids and killing...

Sister knew a guy she went to school with. 15 or 16 year old from memory. Yeah... He murdered his stepfather and attempted to murder his mother. After he committed the deed police found him standing at the bus stop with his school gear, waiting to catch the bus to school as if nothing happened.

Point: some younger people are just mentally fucked up, so having a child killer who has grown up in a murdering world isn't unbelievable.
