It is a death cult that draws spiteful mutants who are angry at God for daring to make a universe that doesn't conform to their whims.

So they lash out by hurting those who are successful partly to prevent the successful from reminding the mutants of their own inadequacy an partly to get revenge on God.

The ultimate goal, whether the proponents realize it or not, is to destroy everything so badly that so frequently that it can no longer be rebuilt. Only then will the malcontents find peace because there will be nobody to show them how it is possible for there to be better.

It is a retelling Cain and Abel and has been playing out since the beginning of our species.
