So now the problem is to figure out just why.

Perhaps they were sinful like those in Sodom and Gamorrah, so God just whacked them.

Or maybe it was more of a general wipeout such as in Deut 3, "destroying the men, women, and children, of every city."

Or perhaps God was angry at Burma's leader, so did a twist of punishing the people instead of the leader, as he did to the Israelites in 2Sam 24 when he zapped seventy thousand because David made him mad by doing what he (God) had told him to do!

Or is it possible that Epicurus had it right back before 270 B.C. when he proposed:

Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?

How do you vote?
