Yeah that is a popular concept by Karl Popper but do you know more about him? Do you now that NeoLiberism (or NeoLiberalism if you prefer) has the same ideological roots of Nazism and both were financially supported by the same powerful people? Those roots is social darwinism and scientism is their way to justify their atrocities, so be careful when citing Karl Popper.
We already have the cultural tools to stop that in Western history and in this case it's Rousseau's division of power: it's not up to me nor to you nor to anyone else to condemn someone by inflicting whatever punishment that affects their lives.
It's up to who has the juridical power to do so with limits, accountability and the guarantees prescribed by law.
Any exercise of power without previously settled responsibilities is authoritarianism and you can't hide it behind a poor rhetorical trick.
