In my brief new age phase (between being religious and deciding it was all bunk) I tried to believe that "everything happens for a reason" and "there are no accidents". I had been through some pretty awful experiences and was trying to make sense of them that way. Some good has to come out of every thing bad, or else we are just at the mercy of chance. Right?
Until reality kicked back in. People don't always get over tragedies; they are sometimes completely destroyed by them. There is not a single good thing that can balance out the genocide of an entire ethnic group, the sexual assault of children, the flattening of a whole town to a tornado, a team of firefighters burning to death.
And it is not just the loss of life and property. Suicide, consuming grief, death by drugs or alcohol abuse, severe depression, PTSD or other illnesses are common reactions to surviving horrible experiences. Some people are never able to recover. They are doomed to be institutionalized, to live on charity or to rely on others for support. These are very painful and costly to families and to societies overall.
You can try to scrape together some good out of the bad, you can look for some positive things that might not have happened otherwise. But for every single tragedy, problem or accident that connects to some good outcome, there is a far less painful, less harmful, less costly way that same positive thing could have come about. That is why "god is trying to do some good" is a piss-poor excuse for bad things happening.
If a god wants our attention, he/she/it needs to show up for real and get it in an unambiguous, obvious way. Let everyone know what god you are and exactly what you want--in clear, easily understandable terms.
Don't send a bunch of crazy-a$$ prophets or mysterious messages on the bark of trees. Don't burn an image of your mom on a piece of toast or a tortilla. Don't send a tsunami to Japan, drop a building on Bangladeshi workers, or run a bus over some woman on her way to work, and hope that we can figure it out from there.
That kind of sh!t is not clear, not nice, and will make me NOT want to worship or even believe!
