Using the elements or His people to carry out His will was something that happened in a time before.God does not do this anymore for He has a set time for Judgment in the near future.Killing his creations because they disobeyed His commands is not a bad thing.it is declared judgment.People confuse the two often.Therefore it would not be considered an evil act.God does not commit evil acts.
James 1:13 When tempted, no one should say, "God is tempting me." For God cannot be tempted by evil, nor does he tempt anyone;
That quote doesn't have anything to do with the question at hand, which is not whether God tempts people to evil but whether he is thought to visit evil on people. Nor does it magically invalidate the well established principle, as stated by
Isaiah, that God is the source of good and all evil alike. If you're going to claim scriptural authority, you don't get to behave as if one verse cancels out another.
As for the other part, I think folks in Laos must have felt the tremors from the shifting of the goalposts. We're talking about natural disasters (i.e.
evil in the literal sense of the word, not the moral sense). Either God is held to be the source of that evil or not. The picture painted by scripture is a consistent
yes, yet you claim no. OK. I would actually be sympathetic to that position, but you also claim scriptural authority, which isn't going to work, for the reasons stated above.
Lastly, even if you could legitimately rebut the point by claiming that God's killing people through natural disasters wasn't
really evil in the moral sense (which you can't, 'cause that's just special pleading and semantic wrangling rather than an actual rebuttal of the point in question), the problem remains that it's a morally reprehensible view. The idea that creating someone gives you licence to torture and kill them is depraved. We do not allow parents to treat their children in that way.
The creation of sentient life does not come without moral responsibilities, nor does being created come with obligations of servitude to one's creator. In all cases, in order to be considered morally good, one must act with compassion, kindness, and love. Failure to do so is wrong, regardless of the relationships involved. If you give God special exemption from all moral precepts, then God's goodness is a meaningless assertion. "God is good because he is God, and God must be good" is called begging the question. It is not a legitimate argument.
Of course, you can say that
Isaiah is wrong and God is not responsible for disasters or any other sort of evil, and that would be fine. But in that case you don't get to have it both ways and say that God is the source of all that is good, as by that point we've already established that phenomena can occur naturally without any divine intervention.
