Yet you think that Hydra would be any different? That's, more or less, exactly the kind of regime that would be imposed if they were to take over for real. There would be no due process of law, there would be (at best) only show trials where the verdict has already been pre-determined and the actual trial would be a mere formality. They've already shown that they have no problems with killing hundreds, if not thousands, of innocents if it means that they get the guilty and for them the guilty is anyone their matrix determines is a possible or potential threat of some kind at some point down the line. How is this different from Krull's ideals now?
Again, not supporting Hydra's particular approach to getting the job done, only that they are trying to get a job done.
It certainly does make one wonder how that scenario would play out and if you would eventually kill off all your most valuable people until you had no one left.
