I think we need to be careful to distinguish between what is hard luck, unfortunate, etc., and what is evil.   To contract cancer, or to have a heart attack, or to have a satellite fall on your head is bad luck or unfortunate, all right, but there's no evil there, and I don't see any conflict with God (or "a god") being good, if you want to believe in a god at all.

Evil, on the other hand, proceeds from human action, and particular from malicious human action. Perhaps I should include greedy or antisocial human action. In other words, one might say evil proceeds from free will being misused.

When bad (merely bad, or unfortunate) things happen to good people, there is no particular contradiction or injustice. When a good person (or any person, for that matter) is the victim of evil (the result, even rather remote sometimes, of a malicious or a self-serving act), we get to the theological dilemma posed by the original poster.
