I’ve witnessed things, that could be described as Karma. Bit the vast majority of my observations, suggest that is not real. In fact, quite the opposite. Bad people, cheaters, etc, often have great lives, with little or no ramifications, for what we perceive as immoral behavior.
Unless, you consider death itself karma. But that would indicate that we have all done something worthy of death…
In many circumstances, there really isn’t a chance for Karma to “react” to. Like a baby dying a slow, miserable death, before it could be capable of even moving much, or thinking much…
