zetas fucked up their own planet because of experimentations and went on to a verge of extinction. with a crumbling home planet and atmosphere they mutated so badly in form and couldn't continue their race line anymore. why do you think they went here and start abducting people?
1. they don't have a place anywhere
2. make hybrid human-zetas to increase their chance of survival bc their form as-is is not fully compatible with this planet
that said, not all zetas for NWO, The Great Reset, black hole fall return to Source. Some zetas have rehabilitated and are assisting the Guardian Alliance to free this quarantined earth and help its people to achieve stargate ascension.
