To fit with the grim dark setting, the greater good may or may not be foisted upon the Tau masses by a ruling caste through some sort of mind control. The utilitarian space communists might be unknowing slaves, dedicated not to an actual greater good but the ruler’s good. And if that is true, that ruling caste may or may not be actually perfectly benevolent truly working for the greater good, having raised the Tau from warring tribes into enlightened space communists. Can’t have nice things in the 41st millinium, gets in the way of all that “only war” you know.
