That is the most interesting question isn't it.
I think some people believe that everything happens for a reason, or is part of someone's plan, and so that's how they cope with tragedy. Although I often wonder if that thought process is potentially more harmful.... I think if it helps people see the silver lining out of every terrible situation then it's probably good. If it means they question their faith, that's probably a good idea too. I do believe everything should be questioned. If there is a good answer, then it doesn't hurt to ask the questions... and if there is no good answer then it stops you from blindly believe something that might cause you harm.
I personally think it would be easier for people to cope with, if they realized that sometimes bad things happen... just like sometimes good things happen... and sometimes a really bad thing (like a car crash) nearly happens but you get out of it luckily. Things just happen. The best rational then is to try and be as prepared as possible... and accept the things that you have no control over. If a bad thing happens and it teaches you a valuable lesson, then it wasn't for nothing.
excellent your answer i share your point of view we simply take god out of the equation.
