Human nature is immutable and freewill will always allow some to follow the path of evil.
All of the wishful thinking and hope of all of the prog-libs in the world will not change these truths. No government power will ever be enough to suppress all human evilness, and in fact, the exertion of such power is always in the hands of humans who are themselves subject to the same truths and liable to follow the path of evil they claim to want to eliminate.
Only the liberty and freedom to live one's life while equally negotiating with others who are also at liberty and free can create and sustain a society where evil can be recognized, stopped and punished.
A government that attempts to make some more equal than others creates evil.
