All these things (judging from history) make morality more complex faster than they iron out the inconsistencies.

Even within a highly complex space of moral possibilities, there will be large moral clusters of near-equilibrium as well as delusional-but-momentarily-stable ones. I got ahead of myself by mentioning Amanda Knox. I think what I really wanted to ask was this: if a particular gene/environment interaction produces near-equilibrium, what happens if everybody else gets vaporized/eaten by zombies/etc? Does the de facto Utopia diversify itself back into ambivalence over time? Can this be prevented/managed?
