"  There have also been reports that the Tau have begun to take a tougher line against some human colony worlds, sterilising their populations so that the human population will die out and leave the worlds open for full Tau colonisation. This policy was known to have been carried out following the Tau conquest of the desert mining world of Taros. Whether this represents a new Tau policy towards all humans or just a Tau desire to reserve the resources of their conquests for their own people, these actions will not be tolerated by the Imperium of Man. "

Not much worse than what the Imperium does, but I believe this should shatter the image of the Tau being good guys. Because lets face it: It's 40k, if they were good guys they wouldn't fit here. Everyone is a bastard and everyone deserves to die in 40k.
