People in the area of the tsunami say that it is their faith that helped and helps them survive.
Good point. The main view of the people directly involved in natural disasters share this view. This is the very conclusion from the majority of victims. This point must be considered.
Cofty
The opium of the people. Like an abused wife who begs for her husband's love.
This is victim blaming cofty.
You cannot blame people directly involved in the disaster if they find the faith in God explanation better than "shit happens". Rational minds search for meaning and these people chose not "shit happens", even under extreme circumstances.
You cannot have it both ways. Mystery and victim blaming are out of your deck of cards.
BTW, "shit happens" to me is an euphemism for secular mystery. So IMHO you can't even use the "shit happens" either.
Instead you should scientifically demonstrate for us why our minds perceiving evil at all (natural and man-made) is an evolutionary advantage.
What was exactly the evolutionary pressure that made us the only specie to perceive evil?
