I would call my marriage very good. We still have problems. Bad stuff still happens to us sometimes. “Very good” doesn’t mean perfect. I guess this is not such a conundrum for me.
Furthermore, in the YEC scenario you have a ‘perfect’ world with Satan running around in it trying to ruin God’s creation. You have an entirely different creation than the one we have now. (How does the nitrogen cycle work in a world with no death?) Essentially, you have a second, unrecorded, creation event where God recreates or un-creates many of the herbivores into carnivores and scavengers and invents lots of terrible things like crop blight and stinging nettles and malaria, just to punish humans. I don’t see how that scenario is less distasteful when it comes to the problem of evil. In that scenario God is proactively inventing every way the world is currently imperfect and going about the act of special creation in an apparently degenerate way, motivated not by love and holiness and artistry, but by a desire to curse his fallen human children.
But I don’t choose my theology or science based on some internal sense of propriety. Personally, substitutionary atonement and the idea of a final judgment are distasteful. But they are biblical. There are lots of things in nature I think are disturbing and unfair and a violation of what I perceive to be “the creation ideal.” I don’t think we have the option of denying reality (in science or revelation) based on our preferences. When it seems like science and revelation describe different realities, we have to do our best to find out which description is most compelling and reinterpret the other description to fit. I am happy to grant that there is disagreement among sincere Christians about what is most compelling when it comes to interpreting Genesis and the natural history of the world. But I don’t think it’s a good idea to boil it down to a matter of taste.
