Saintliness
Summary
Some people have argued that, though the presence of evil in the world is clearly not a good thing in itself, it is justified because it can lead to greater moral goodness.
Evil allows the supposedly greater good of this kind of triumph over human suffering.
However, such a solution is open to at least two objections;
First, the degree and extent of suffering are far greater than would be necessary to allow saints and heroes to perform their acts of great moral goodness and besides, much of this suffering goes unnoticed and unrecorded, and so cannot be explained in this way.
Second, it is not obvious that a world in which great evil exists would be preferable to one in which there was less evil and as a result fewer saints and heroes.
