If, that is the case then, criminals, thieves and vandals, would not be caught, and there would be no jails nor prisons. Also, there would be no Police, there would be no traffic tickets. Karma works, whether you want to think it does not.
Also, every time we step outside the door, we work on hope and faith(belief)same as belief in Karma. We hope for a good day, synchronocity, a lucky day. We hope not to have an accident, not be ticketed, to be on time, not to be mugged, nor to get into a fight, the list goes on and on. So you see, your reasoning is a fallacy. karma is very real.
Ok, so "bad things happen to good people" too, huh? I think the balance is shifted more to the "bad things happen to bad people."
Lastly, Karma really has to do with 1. The sum of a person's actions in this and previous states of existence, viewed as deciding their fate in future existences.
2. Destiny or fate, "following as effect from cause."
Following as effect from cause is how Wiccans use the term Karma.
You get it? Cause and effect? Cause - Do something bad, Effect -you get punished here or by Divine Retribution "Karma"
Whatever dude. Blessed Be.
