Ok, I read something about that on wiki the other day.

wiki paragraph

What is this “Legitimate duty”? Something the local government decides on? How far will they allow violence to escalate as justified self defense? In the past, various country used preemptive strike, is that allowed? Sounds to me they are indeed capable of violence….

Somehow, I think you found another Shangri La. There’s no perfect and peaceful religion because violence is a necessary part of life. Like I said before, violence is merely an action, a reaction, and a tool to achieve an end. How you use that tool, how much and when you are using that tool, that’s the practical question.
