For that matter "cruelty is the point" might also be a slogan, but is also very correct observation.
For reference, here is the Wikipedia definition of conservatism:
"Conservatism is a cultural, social, and political philosophy and ideology that seeks to promote and preserve traditional institutions, customs, and values. The central tenets of conservatism may vary in relation to the culture and civilization in which it appears."
Overall: I would argue that conservatism is a confounding variable in the events you're observing. What's actually causing the things you're observing is centralised power and authoritarianism.
It's exactly what "conservatism" has always been as a political ideology since it emerged as a coherent thing as the reaction against liberal/left politics (originally two different names for the same thing in different places, though they have since diverged in common use somewhat).

Conservatism is (in relation to any of the societies in which it has existed since it emerged, not a hypothetical way the term might be used in some other context) retaining and reinforcing the centralization of power in established elites against the pressure from liberalizing forces to distribute power outward.
