If it is a valid excuse for violent people that "I just have to follow the orders that given to me!" , history never judged SS soldiers or war criminal!... If we support and define strongly that people are creatures who can think! more than all livings... So, there is one responsible individual for that we have done! We are...No matter which authority we have to serve or we have to follow! If we decide to fight somebody who attack us, the reason of our behavior is not their attack! The reason of why we chose fighting them is that our decision! Nothing more nothing less... No matter what we are doing. The owner of behavior is the owner of behavior.
