George Orwell: "If you want a vision of the future, imagine a boot stamping on a human face - forever."
The Tzenkethi civilization is the materialization of this prediction, in its purest form - that can enable a relatively long-lived civilization, that is.
The Cardassian civilization was ever only a contestant to this title; ultimately, it fell short.
A person who desires to live in the tzenkethi civilization is a person who wants to be nothing more than a mindless tool. Its choice is irrelevant, by its choice - much like it's nonsensical to consider what a computer wants -, because it forwent anything resembling free will.
At most, one could wonder about the extreme psychic deviancy that leads to such a choice.
