You are all correct. Thats why the article stated what it did. Children killing animals is very serious and can lead to extreme violence when older. I believe these children not only need mental care but they need to be watch by the system for years to come. I just hope the system doesn't fail these kids or society.
I believe that any parent who would let their kids play this type of game has an issue. I mean I wouldn't let my teenage son play this violent game and 6 year olds are playing it. Definally intervention is needed.
