There is no more hideously evil act than trying to establish a government against a free society. Or anywhere. Some other actions are equally evil, but none more so.
And make no mistake- every "government" is against a (possibly hypothetical) free society. You have freedom- and civilization- in reverse proportion to the amount of "governing" imposed on your society. Some of the effects of "government" can be mistaken for civilization, but if that's all that gives the illusion of civilization, then you have no civilization.
Sure, if everyone in a society is evil, then less freedom might be good. But where do you get these people who will govern? And how do you keep them from becoming evil? (You can't.) At best you are switching out one evil for another.
In this case, "best" isn't good enough. It isn't good at all. In some cases self defense or escape are the only reasonable options. Establishing a "government" never is.
