but it makes for a much more interesting and political universe where war would, hopefully, be more common.
morality in CN is made by the powerful to keep them on top and subject the lower alliances to their morality. Lower alliances do not dare violate this code, in hopes of staying alive and these small alliances get so wrapped up in the morality that they accept it themselves. Now, what Jack wishes is to defeat the morality at the top level, but what it would actually do is prevent people from doing what is politically advantageous to their alliance and prevent war (that is, if people conform to Jack's morality because they fear his attack), which would conflict with Jack's goal of ending stagnation.
Jack's idea would be beneficial if their was a domineering power, like there was pre-Karma war, because it represents an entente that will not conform to the morality of the top alliance. Those conflicting moralities would war and create anti-stagnation because there is no single power over the cyberverse because we are not dominated by one alliance/morality. However, we have multiple powers and multiple moralities vying for the top spot (eventual conflict) and Jack's idea would do the opposite that is intended by subjecting us to a single morality via his violent means.
