What I find interesting is that Chris Kyle is a hero and Robert Bales gets life in prison without parole.
Your comparison is absurd. Robert Bales murdered 16 Afghan civilians (9 whom were children) by going into their homes and shooting them for no reason after he was drinking.
Chris Kyle shot armed combatants that were trying to actively kill American soldiers.
There is no comparison between the two situations. That you are trying to push them as equivalent only demonstrates how completely twisted you are.
