Are "logical" and "rational" objective classifications of a person's actions?

[One Above All]

For example, when scientists look at evidence, they look at it objectively: the evidence is there, now they have to understand it. In this case, "objective" means that you're not projecting what you would have done, given your own values, morals, way of thinking, and so on, but rather what should have been done, regardless of one's values, morals, way of thinking, and so on, to achieve the goal.

The way I see it, "logical", when applied to something that is inherently subjective (a person's actions and desired outcome), is en par with "absolute morality", in that they're oxymora. People's desires are not universal, so the use of the terms "logical" and/or "rational" when classifying what someone did is illogical (see what I did there? Seriously though, see what I did there? In my view, the usage of these words is illogical, but, in your view, it's not. This is because we have different PoV's. If there were an objective PoV, we'd be able to say whether or not this was, in fact, [il]logical).
