Yes: A lie to boost the morale of a country fighting a defensive war against a genocidal dictatorship is unambiguously a better lie than the lies of the genocidal dictatorship to rile up its populace to more effectively execute the genocidal war.

My country lied to its populace during WW2 to boost morale in its fight against Nazi Germany. Nazi Germany lied to its populace to more effectively execute the holocaust. They are not the same.

So it's true, not all lies are equally bad, hope that helps. Most learn that as children.
