According to this moral theory an action is wrong because it cannot be universalized?

This statement aligns with the moral theory of Kantian ethics, developed by Immanuel Kant. In this theory, an action is considered wrong if it cannot be consistently applied as a universal law without leading to contradictions or logical inconsistencies. This idea is encapsulated in Kant's principle of the categorical imperative, which states that individuals should act only in ways that they would be willing to see everyone act in similar circumstances.
