my working theory for a long time now is that the number one and most effective measure against evil people is shunning them, avoiding doing business with them, and not referring other people to them
a potential situation in which good people could dispense with that evil 1/3rd is in a case where if you are not evacuated, you are killed by your stupidity
moral obligations are negative, not positive
you are not obliged to help anyone, but you have a mutual benefit from helping someone who would help you if the roles were reversed
thus, yes, if i was someone who wanted to fix the problem of evil for human society i'd use the opportunity of an unavoidable catastrophe as a time to "reap the harvest" of righteous and leave the evil to burn
that's basically what i think that Revelation and Enoch both outline as a long planned strategy for this (i'm not against the idea that the good can be resurrected also but i have no model for what this looks like or how it can be done)
