if karma does exist, and you wish a karma for someone because you were persecuted, how if the current persecution was actually your karma?

i did her wrong, than you did me wrong because i did her wrong. it was a karma for me, no? later, someone did you wrong because you did me wrong due to what i did to her.

and someday, someone else will do wrong someone who did you wrong, maybe by the one who i did wrong.

since karma is a cycle of cause and effect, my last thought makes sense.
