Suffering caused by natural occurrences are known as “physical evil”. Those caused by sin are known as “moral evil”. The main difference-and what makes moral evil so much more, well, evil, is when sin, especially the most grave or serious kind, is committed by a rational, free moral agent *with full knowledge and deliberate consent, *someone who could’ve done otherwise IOW, and refrained from the sin. Physical evil is beyond human control-we naturally perceive it as bad but not to the same degree as moral evil, when both are directly experienced-because moral evil always transcends or opposes reason and justice.
