This is prompted out of the way the Amazons are depicted in Wonder Woman: Dead Earth, but is really more general.
Back when Marston created Wonder Woman, he also created a social context for her in the form of the Amazons. The Amazons served two different narrative roles: the first as the environment that shaped and created Diana, the second as the ideal that Diana wanted to spread as she went to Man's World.
Diana is presented as a hero and a good person because she was raised in a loving and nurturing environment. Even if she is molded from clay, she was crafted from love and raised as one of the Amazons: from a social perspective she is the best of them, not better than them or different than them. Her ideals and values are the Amazon ideals and values. She was also a wanted child. There were no purposes to her birth, from the point of view of Hippolyta, than wanting a child.
In this way the Amazons are similar to the Kents, Superman's adoptive parents, who acts like representatives of an idealised America. The Kents literally takes in the homeless, tempest-tost Kal-El, raises him as their own, and infuses him with their ideals.
When Pérez rebooted Wonder Woman he added some nuances to this template, but the core remained: Diana was a wanted and loved child, and she was raised to embody the Amazon ideals. Even if she was richly blessed by the gods, it was the Amazons who shaped Diana as a person.
Pérez also introduced tensions and fracture lines among the Amazons with the creation of the Bana-Mighdall, but this had no impact on the relation between Diana and the Amazons of Themyscira.
Various other depictions of Diana and the Amazons have introduced their own variations on the theme of the Amazons as a family.
Gail Simone introduced tensions within Amazon culture that were organic to it with The Circle, but fundamentally it didn't change the relation between her and the Amazons.
Azzarello crafted an entirely new relation between the Amazons and Diana. She is called "clay" and depicted as different from them. By the logic of superhero narratives, that also means that she suddenly is better than them as well. Her training and values are also depicted as coming not only from the Amazons, but Ares too. Then we get the reveal of the murderous rape Amazons and their male children. Diana's role is now not to save Man's World with Amazon values, but to save the Amazon's from their own values, and to save Man's World from them. It turns Diana away from being a hero of change to Man's World, and towards being a protector of the status quo.
Rucka's Rebirth couldn't change everything that Azzarello had introduced, but it fully brought back a Diana who was of the Amazons. They gossiped about her, she had friends, and was a full (if junior) member of the Amazon society. Rucka created tension between her and Amazon society not by having her be treated differently by the other Amazons, but by having her longing for and curious about the world outside Themyscira.
The 2017 movie is somewhat contradictory in these themes. The Themysciran parts of the movie very much presents Diana as one of the Amazons and a product of their society. There are differences between Hippolyta and Antiope on how to raise and train Diana, but she clearly is of Amazon society, and the values she learns are Amazon values. Hippolyta's grief over Diana leaving is also presented as the grief of a mother for her child leaving home.
Ares's revelations change things a bit, since Diana was created from another purpose than longing for a child, but it is overshadowed by the on-camera depictions of little Diana growing up among her Amazon aunts. The movie's ending also affirms Diana's belief in the Amazon values, though now tempered through her contact with Man's World.
Morrison's Earth One again places Diana as an outsider. She was not conceived or crafted out of love, but as a way to get revenge on Heracles. She is also presented throughout as a partial outsider, by not being allowed to participate in every part of their society. She is also drawn as physically different from them. Diana is presented as an agent of change for both Man's World and Themyscira, but it is Themyscira that is depicted as the one most in need for change and reform.
So where is Wonder Woman Dead Earth here? We haven't seen the full story yet, but Diana's creation is again predicated on not longing for a child, but that she should be crafted as a protector and weapon. Her training and upbringing isn't in values or in being the best person she can be, but in order to control herself. Themyscira is also presented as a refuge first, not a refuge that has been made into a paradise. Diana is also again set up as a protector of Man's World, against her own family.
To sum up, I think that Diana and the Amazons are narratively co-dependant. I won't say that it's impossible to examine and build up Diana by tearing down the Amazons, but they are literally the foundation she needs. A close examination of Amazon society can probably be done, but it needs to be done really carefully. So far, I think only Gail Simone has managed it amongst the main Wonder Woman writers.
