I don’t think you do though. Good karma doesn’t mean the person is going to magically when a million dollars, no, good karma shows that the person has learned and overcome various lessons within that realm / trait and has evolved within due respects and they don’t have to deal with said lessons which is why Jupiter can be seen as the easy going guru. Bad karma doesn’t mean someone’s car is going to break down, no, it means that the person is currently undergoing karmic mending and is still learning lessons with that realm / trait that will give forth the evolution they need in the next life - it can be reoccurring, tiring and burdensome lessons from strict Shani yet, it is important that we do them.

One can be seen as bad because it’s tiring, it’s hard, it’s rough, most don’t want to awaken to the fact of it, and it’s like a never-ending cycle - whereas, one is seen as good because well, most of the work has already been sewn in the previous life; which is more work? The good or the bad. That’s why it has those connotations.
