I found it interesting to read about the psychological impact on parents and children after that Tsunami. The main faith groups of the Indian Ocean basin are Islam, Christianity and Buddhism.
Of these groups the impact was worse amongst the Muslims, who found such a tragedy, incompatible with the actions of an all loving "god". The next group, most traumatised, were the Christians. These, Cofty, struggled with explanations as you so admirably put to text.
However, those who seemed to come to terms with the tragedy and loss the most... were the Buddhism. It was "mummy and daddy's" time to rejoin the Universe. Their "spirits" lived in the trees and they would accept that it would be their time one day to rejoin the rest of the Universe. The hurt prevailed, but it was not attributed to an all wise and loving Creator. Simply, that we are part of a "whole" Universal cycle. Our destiny is influenced greatly by our Genes and our Circumstances.
When we can, we move away from danger... we don''t build hospitals on the San Andreas fault line, for example!)... and do our best to string out our existence.
Of course, if You are a dyed in wool Atheist... you don't have the luxury of any such reasoning. Maybe that is why Atheists have the lowest retention rate of their Young ( and you guessed it, the JW kids are not far behind!).
All the best to all, for the New Year
