[40k] Is it possible for humans who are taken into the Tau to be redeemed in the eyes of the imperium?

I understand they would be considered traitors to humanity but in alot of cases it could be argued they were simply left behind by the imperium and had their systems occupied. Is there any case of them being forgiven by the imperium? Further more if this is a thing what would the Tau treat them as?

It really depends on who shows up to do the redeeming.  Lost worlds are, to this day, routinely discovered and brought back into the fold with nothing more than a declaration that they will accept the Imperial truth, worship the Emperor, and contribute to the imperial levies.  A commander who makes the call that this is a lost world being returned to the fold would not be questioned unless a particularly strict Inquisitor happened to be around.

At the same time, a commander who decided these people are filthy traitors who joined the xenos instead of doing their imperial duty and dying to the last man would *also* not be questioned.  If it's an Inquisition ship that shows up to do the redeeming, youd better bet they'll be purifying the planet instead of redeeming the population.
