Classical failed scenarios. Great morphological/structural changes need legal constraints to don't become very common, or be risk-averse, to prevent the creation of inumerous subgroups with alien values. But contra this, subgroups could go astray far enough to don't be caugth, and make whatever change they want, even creating new subgroups to torture or kill. In this case specifically, I assume we have to deal with this problem before structural changes become common.
