I hesitate to describe the current government as an "administration", because it is not that, obviously. An administration is an organization that executes the policies of Congress per the Constitution and operates in accordance with US law. This cabal is the opposite of that, so I describe it as a "regime".
The issue at present, though, is "how to describe it?" Merriam-Webster provides this guide:
A Lesson on 'Unmoral', 'Immoral', 'Nonmoral', and 'Amoral'
"All of them have prefixes meaning "not." So which to use when?"
As I approached this question, I rejected both Unmoral and Nonmoral. The first, as, collectively, this is a group of humans working together, so sapient. The latter because the subjects are certainly those that are "usually subject to moral concerns". Left with the choices - moral, amoral, or immoral - I concluded there is only one appropriate conclusion: their actions are based upon immorality, "conscientious rejection of typical moral standards and has a connotation of evil or wrongdoing."
Discuss.
