There aren’t any “good people”
- one could as easily ask, “Why do we, who are sinners, & admit we are, not suffer far more ?” Seriously. But the question seems to go unasked.
As for physical evil - part of the answer may be, that a hurricane that devastates a city is not evil at all, but is, as such, a very good hurricane: it is doing what any well-behaved hurricane should. Hurricanes are meant to behave as hurricanes do - & it is.
Unfortunately, the goodness of a hurricane is compatible with the doing of great damage to buildings, animals, & people. This doesn’t mean it is wrong for those people to be in the path of a hurricane - only that what is compatible with being a good hurricane, is not necessarily compatible with being a healthy human being. The two goods are ill-adapted to one another - if the people in the path of the hurricane were a thousand miles away, or if the hurricane were blowing itself out over an ocean, both people & hurricane might carry on functioning as the beings they are, & no one need be hurt. But in fact they are at close quarters, so the hurricane is thought bad because it has in fact killed people.
Crimes are almost entirely good - the problem is that good things are combined in a way, & with an intention, that is bad. The separate parts of a crime may be very good - put together, the result is morally evil. It is bad to commit fraud - it is not bad to have the ingenuity, patience, ability to plan, the intelligence, & other intellectual gifts that make the commission of a fraud possible.
So causes of good & evil are often made up of thousands of other causes; an evil, is sometimes a good thing in a context in which its goodness will mean harm for something or someone else. Which if correct may mean that God allows evil because what is called evil is not evil as such, but lots of good things in combinations which have evil effects. Evil is not a thing as such - it is the absence of a good that ought not to be absent; it’s not a being, but a relation between beings. Maybe there is more than one issue here… To abolish evil, might amount to abolishing good things. Such as the will of man. For God to destroy it, in order to prevent sin, might even be to play the devil’s game, since the devil is the destroyer. Whereas God can use even evil for His own Good purposes
Which won’t explain why God allows Ichneumonidae to reproduce in the way they do.
