This reminds me somewhat of the Lisbon earthquake of 1755
A very religous community in church on all saints day. Most of Lisbon was destroyed. Voltaire seized on it when he wrote Candide saturizing religious notions like "we live in the best of all possible worlds" and "All is for the best".
Of course the Lisbon eathquake was one event that helped to crystalise modern atheism but it relied on having a doubting intelligensia already in place. I doubt that exists in Haiti!
As for other countries generosity we tend to focus on our own and western countries are in the best position to provide immediate technical assistance.
Here for example is a breakdown of donations for the Boxing day Tsunami.

But Saudi Arabia gave $30 million plus an additional personal $31 million donation. Remember that some countries "donations" have a habit of coming out of existing international aid budgets and some (the US in particular) comes in terms of trade credits for goods and services from the US.
The huge Military aid about $2 billion a year the US gives Israel is US foreign aid much of that goes straight back to US arms manufacturers.
Then articles are written about how the US is the worlds most generous nation in foreign aid
