Insanity is doing the same thing over and over again and expecting different results. So, I'm not saying we shouldn't do anything, though that might would be better than repeating ourselves over and over again in an infinite negative feedback loop, manufacturing that which we seek to eliminate. For every innocent life that has been taken a hundred revengeful combatants are born from that persons friends and family.
>The ultimate weakness of violence is that it is a descending spiral, begetting the very thing it seeks to destroy. Instead of diminishing evil, it multiplies it. Through violence you may murder the liar, but you cannot murder the lie, nor establish the truth. Through violence you may murder the hater, but you do not murder hate. In fact, violence merely increases hate. So it goes. ... Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.
