If this man did not experience "karma" (or moral payback or whatever you want to call it) how could it possibly exist for anyone else?

I'm not saying that karma is perfect, or that everyone gets exactly what they deserve. What I am saying is that there is some effect of your actions on your own life, as described above. It doesn't mean that good things will always happen to good people, or bad things will always happen to bad people. What it means is that it is more likely for good things to happen to good people.
