Final answer:
The secular concept of evil views it as a human creation and not an independent force or existence. This perspective sees good and evil as subjective concepts and posits that any perceived evil is actually a necessary part of a world created by an all-perfect deity.
Step-by-step explanation:
The secular concept of evil encompasses the idea that evil is not an independent being or force, but rather a human creation. According to this viewpoint, the concepts of good and evil are subjective and exist solely in human perception.
Leibniz and others have tackled the Problem of Evil by reconfiguring it as a human construct, rather than an inherent aspect of the universe. They argue that if a deity is all-perfect and creates the best possible world, any perceived evil is actually a necessary part of that world's overall goodness.
