1) Is the recent tsunami in Southeast Asia an example of God's willful and wrathful intent to inflict punishment, vengence, or some other specific intent?
Yes. Yes it is.
2) If God intended punishment or vengence, for what specifically?
He was trying to punish Christian missionaries horning in on Muslim turf.
3) If God intended punishment or vengence, why did He choose a disaster that disproportionately drowns or otherwise afflicts women, infants, the weak, elderly, and affirmed individuals rather than inflicting a punishment that specifically targets "evil doers?"
That's how he's always done things. Read the Bible. He kills sinners. All have sinned. He drowned the Christian missionaries didn't he? That's what counts. He's sorry about all the dead Muslims but hey, isn't it worth it if he can nail those sneaky Christians?
4) If the tsunami is an example of God's Wrath, and God is an omniscient being, then He must realize the after-effects such as cholera, typhoid, starvation, death by thirst, diarrhea, dehydration, exposure, etc.; are those afflictions also God's intended wrath, and if so, are the relief efforts actually a work of mankind against God's Intent, hence "SIN?"
Yes, he does realize all that and yes, they are intentional side effects. He wants you to remember who you're dealing with. Our God is an awesome God! And yes, the relief workers, the Christians anyway, are working against his will. If he hadn't wanted all those people dead he could have prevented it. No problem. But hey! There's plenty more where those came from. And besides, they're all in heaven now. Or hell. Nothing we can do about it.
Besides, as long as he's building the Himalayas, there's gonna be some shakin' goin' on.
