The horrible reality of humanity is that people follow orders they shouldn't, because you don't want to be the only person to say no, achieving nothing. It goes even further in the Stanford prison experiment. That's why autocratic regimes like Belarus's persist long after everyone knows they have no legitimacy.

Also, (Re: "PRC supporters and enablers") I assume the vast majority of the people working in the Chinese government are decent people and have never had to do anything immoral.
