Yes, because the character advocates anarchism in the show. But Zaheer's ideology is a flawed understanding of actual anarchist philosophy, anarchism doesn't advocate for chaos at all. Later in the show Korra is supposed to reflect on her nemeses and their contributions and arrive at the conclusion that their views hold some water and ought to be considered, but that they all took their ideologies to the extreme.
Call anarchism an extreme all you like, the relationship between individual and state will always be an antagonistic one, the state will always gravitate toward authoritarianism and usurp more and more rights and freedoms from the poor working majority, the state also maintains a system of castes and protects and defends the interests of privileged wealthy minorities. That is an extreme system.
