I disagree with the bolded part. If a policeman has just finished giving a presentation to a school about avoiding violence and peaceful resolution and then on the way back to the police station is forced to shoot a criminal to prevent a murder, is he a hypocrite? I would say not.
Many Karma alliances have shown that they are merciful in victory when they could have easily imposed NPO-like terms, just look at the outcome of MK-UBD war. However this war is, or should be, about breaking the back of the bully of CN, and I have absolutely no problem imposing harsh terms to do that. And like in the example above I find no hypocrisy in saying that in general I am in favor of light merciful terms, but in this case when we are dealing with people who for years have delighting in curbstomping with the slightest provocation and then crippling their opponents with terms long after the war was over, I am in favor of harsh terms.
