I never look at things the way the opening post asks.
Example: The World Trade Center buildings came crashing down on Sept. 11, 2001, but a NYC firefighter/paramedic dragged a victim out and had to stay with the victim all the way to the emergency room. That same firefighter/paramedic met a nurse that day and they fell in love and married and have a ten and an eight year old child today.
I don't see that as a reason to say "It wasn't all bad." I could also have put my example in the Nazi prison camps.
Any good that came of it was "IN SPITE OF IT," not credited to the cult. The price overall for any good was too high.
