What about a tsunami like the one we saw in 2004? 280,000 people died. That isn't a matter of free will, there is no way it could have been caused by humans. 280,000 people died, leaving presumably many more to mourn and grieve over their losses. Any God that sees this and does nothing is either impotent, or evil.
The saddest thing in regards to the Boxing Day Tsunami isn't a Christian view of it, but rather the Hindu/Buddhist views that many of those affected by the Tsunami believed in.
There were a lot of people who weren't overly distraught at the deaths of children, because by their views, those children had bad karma in their previous lives, and their death in the tsunami was punishment for their previous incarnation.
To me, that's a really tough view to hold.
How could you have a child but live with the thought that they could be punished severely in this life for something they have no recollection of, but their soul was involved in.
I have trouble understanding that more than the idea that they were sinners in their current life.
