Dialectics is a form of triangulation. Not at all 'just' dual, with a possible third deduction as novelty, consensus or conclusion. The thesis–antithesis symbolizes uncountable potentials for an uncountable potential of syntheses. As long as we see this as a method of intelligent practice and creation it can not be seen as inherently good or bad. The method just is.

”Hegel's dialectic is the tool which manipulates us into a frenzied circular pattern of thought and action. Every time we fight for or defend against an ideology we are playing a necessary role in Marx and Engels' grand design to advance humanity into a dictatorship of the proletariat. The synthetic Hegelian solution to all these conflicts can't be introduced unless we all take a side that will advance the agenda.” Niki F. Raapana and Nordica M. Friedrich, THE ANTI COMMUNITARIAN MANIFESTO

This I would contend is when the individual being has ceased to be otherwise inherently creative and intelligent, by indifferently giving this power away to others or by force taken away by others.
