God doesn't "murder" anybody. There is death, a result of a humanity that once sought to be like God. And death happens in many ways.
Instead of imputing "motives" to God when there are hurricanes or natural disasters, large numbers of believers choose to do what they are able to alleviate misery and suffering. Like Job, we overcome the temptation to question why some of these things happen, because we know that Our Father knew us from all eternity, created us, and loves us immeasureably.
You don't trust God very much, do you? If you did, you wouldn't be so concerned with your miserable tax dollars going to alleviate human suffering.
If we can do it when there's a tsunami half-way around the world (which I'm sure some objected to also), we had better do it when our own people are in trouble. I can think of far less necessary things my taxes go for.
Who among the dead in Mississippi "sought to be like God?" And even if they had, who put that desire there, and then killed them for it?
