I don't believe in karma as some kind of magical thing. However, if someone does something cruel or unjust, while they may get away with it in the moment, longterm trends will absolutely have an effect on their interpersonal relationships or maybe even their criminal record. With the opposite being true for positive actions. So in some ways yes I do believe karma is real, it can just be extremely delayed and not for specific actions.

Karma exists!!!

I'm sure that the bad you do comes back to you in some way. As my mother used to say, "Do good and don't look at who it's for." I grew up with that saying and many more!

How do you define karma ?

the way i understood it:
Karma simply means action: your action, your responsibility. It is not some external system of crime and punishment, but an internal cycle generated by you.

Accumulation of karma is determined only by your intention and the way you respond to what is happening to you. Over time, it is possible to become ensnared by your own unconscious patterns of behavior.

karma means action, or in the broader definition: the universal law of cause & effect; every cause has an effect and every effect had a cause; anything u do now will come back to u sooner or later as a reward or a punishment, as a desirable or an undesirable effect, and yes, we are all experiencing the effects, sooner or later, including the man or woman that initiated the cascade;

wrong actions eventually punish the initiator, whereas correct actions eventually reward the initiator; a wrong action is that which does harm to other sentient beings; a right action is that which does no harm;

the dark occultists are able to postpone the punishment to themselves by having order-followers do their bidding, thereby letting someone else receive the karmic punishment first; all order-followers are dumb unconscious people who constantly suffer the consequences of following orders;

as a result of this abstraction, it seems as if the dark occultists (ancient bloodlines, master manipulators of human consciousness) can keep the chaos going indefinitely... however that is not so - eventually the effectiveness of the psyop ends, and the karmic law gets to them also;

the prison region that is planet earth has been reset thru violent destructions several times in the attempts to postpone the karmic punishment to the dark occultists indefinitely... however, this scheme will not last forever, because the universe always brings things back into balance, however long it takes, despite the multiple destructive global resets;
