These pro-Sentinel arguments make no sense. Humans are not going extinct because of 'evil' Mutants. They're going extinct because of evolutionary factors. Sentinels, nanites and inhibitor collars don't change that. Unless you use them to commit genocide, which is what has happened and will continue to happen..
Parents should want their children to exceed them, to be more than they are and to achieve more. Orchis is really about parents who don't want that and feel threatened by their offspring's success. It's good that Gregor didn't have kids because she would've been a horrible mother, in addition to being a horrible monster.
