Esquilax--are you assuming that God causes an "evil" event or allows an "evil" event? There is a big division in Christianity between these two positions.
I don't think that the position that God causes an evil event to happen is defensible logically nor an accurate interpretation of the Bible. So, your argument that the "God's mysterious intentions...is irrelevant...because motives aren't the sole determining factor when deciding moral issues", does not progress your hypothesis because then motive is not an issue.
