I mean, the monks are powerful enough to change reality on a grand scale (mass mind-altering, giving The Key a form) so they should be powerful enough to just open a portal and let Glory go home or expell her from Earth's dimension. Boom. Problem solved. If the puny beings of AtS can open portals every Sunday, surely the monks could. But nope, they found it better to steal Buffy's eggs (without her consent), I mean blood, create a child with her eggs (without her consent) and then forced Buffy/Joyce to take care of and protect said child (without their consent) and putting their life in mortal danger which definitely killed Buffy and probably killed Joyce. And topped it off with altering the minds of hundreds, if not thousands to accommodate Dawn's place in the universe without their consent. And they didn't even have the decency to pay child support. But it was accepted as the 'right thing' by the narrative via the characters. All these violations? Pft who cares. The child is what matters, nothing else. Just ask Buffy in The Gift who chooses Dawn over the world.
