Uh... It was [i]never[/i] supposed to be gray about whether or not Galatec were villains. I mean, they probably don't see themselves that way, and they [i]do[/i] keep people pacified, but that was never supposed to be presented as good. The only moral grayness that was ever supposed to come from this was how the brainwashing will have the general populace against the rangers (for a time).
