There are no accidents, or so claimed Carl Jung in his work on synchronicity, positing that events may be connected causally or by meaning. Some people see this as the work of some karmic force whilst others use it to suggest that a person is being passive-aggressive.
I’m not sure if the bible story of Judas and Jesus is really a karmic anecdote, but under this paradigm, everything is a no-fault situation. Judas was fated to betray Jesus. And despite this lack of responsibility, Judas still committed suicide once he realised what he had done and despite it not being an accident.
In the passive-aggressive sense, it is to say the event A may be caused by something in person B’s unconscious mind—and not by some collective consciousness or a Universal Overseer. So, secretly, if Person B accidentally backed into your parked car, it may not be by some conscious volition; rather, it’s because or some deep-seated anger or other ill-will harboured and directed for you.
The problem is that if you accept that there are no accidents, then you—intentionally or otherwise—parked your car in a place where it would necessarily be hit by someone—by anyone. It just happened to be this other person for whom there are also no accidents. So, both parties are blameless. But people love to blame, and they like to defer responsibility.
The bottom line is that both of these concepts are a bit sketchy. In a world of no free will, the karma situation might be plausible, but this wreaks havoc on moral-ethical systems. I discuss that in most post on karma.
