The mere judgment of things, like someone murdering being a murderer, or other characterization that describe behavior, are implicitly applying a judgment of good or bad without needing to say it. Saying it is an explicit description of the behavior, which is valid to say. Anyone has the right to speak and judge. Everyone has good and evil potential in them. It's their actions that speak to the manifestation of the inner good or evil, right or wrong, truth or falsity.
