"Don't let perfect be the enemy of the good" and "ends justify the means" are not equivalent, nor does the first imply the second. The ends never justify the means. Full stop.

Unity of thought and behaviour has a huge inherent advantage over disunity, and thus authoritarian ideologies often triumph even when only a minority cleave to such. That doesn't mean those who value diversity of thought and behaviour should embrace groupthink and obedience to combat this advantage, though. Temporary measures have a tendency to become permanent, there's always another crisis where dissent and criticism seem inconvenient and counter-productive. It is - but it is also vital.
