I don't believe that people should suffer in order to learn lessons. I don't believe the only value that can be gained from an experience has to be one that brings pain and trauma.
There are people who think that painful, "crash and burn" failures are the only kind of failures that propel people to greatness or that there is only value in what you learn if you suffered to learn it.
You didn't "suffer and turn out fine" if you truly believe other people should have to suffer in order to grow.
