AIBU to ask if you believe in Karma?

No. It’s a very silly notion people believe to make themselves feel better.

Not karma per se but horrible people I may come across are likely to be like that with everyone and will therefore suffer the consequences at some point.

No, but some people do get the consequences of their own actions. Like when you have been a horrible bitch or bastard to a colleague who is then promoted above you and will not exactly go out of their way to help you.
When you cheat and then get cheated on, as your affair partner is clearly fine with the idea of affairs.
When you cry wolf and make up shit, and later nobody believes you.

I havve many examples of those situations.

I don't think there's karma as in a simple tit-for-tat on a universe level, no.

I suppose what I believe is more akin to "one good turn deserves another" ie if you are a kind person there's likely to be more kindness around when you need it, which you will at some point because no-one can avoid grief, death, illness, redundancy etc forever.

I do sort of believe in it. I’ve seen it happen many times in life but it could be just coincidence. I do think that showing kindness to others makes your own life happier. No evidence - just my own feelings and experience. I have no religious faith so I guess I look for other things to believe in

My first husband left me after 12 years for someone else.
We met very young age 16/17.
I was devastated and had a 1 year old baby.. l had a breakdown.
7 years later the OW left him for someone else.
He rang me up.. ( l had re married and pregnant and happy at the time) to apologise (while crying )for what he put me through 7 years previously .. because he now knew how l felt when he did it to me.
I think that is what you would call KARMA!
So yes l believe.

Sometimes, to an extent. Being nice won't stop bad things from happening to someone. But a nice person is more likely to have people around who care and want to help.

I had someone at work do something unnecessary and not pleasant when competing with me for a promotion. It felt awful, so I withdrew my application and started looking for other jobs. She got the promotion... and it went so badly that the entire team revolted and her post was eliminated. Karma/consequences of being nasty 🤷‍♀️... either/or

Well my ex husband ( horrible abusive cheat of a man) is now unemployed, living in a shitty rented flat while I’ve turned my life around and have my own home and a good job so perhaps. Whatever it is it makes me chuckle.

Yes i do think what goes around comes around and a bad deed or behaviour often slaps the perpetrator round the face at some point in the future.

Yes, it’s the only way to cope with the way that my husband’s stepmother has treated the family since his fathers death. She is a horrible wicked person and one day she will get her comeuppance and it will all come back to bite her.

No, though I do wish it was real.

Yes, my df died of lung cancer. He had a horrible death. His "partner" was awful. The first thing she did was use his debit card to go to Tesco 30mins after his body had been taken to the undertakers. She and her daughters took out the max amount of cash from his current account every day while telling me and my brother thst we didn't need to rush to deal with banks and paperwork. She didn't pay a penny towards the funeral.

She died of lung cancer too a few years later, with a much longer drawn out illness.

It doesn't offer comfort or make me feel better but yes I think this is karma.

No but wish it existed

Of course not. Our life experience proves time and again there is no cosmic force guaranteeing that bad things come back on those who deserve them and good things to good people. Sometimes good or bad actions can start a chain of events that make it appear that way, so a horrible person ends up with no friends, for example, but that's just basic actions and consequences. No higher power involved. Personally I really hate the idea that people who are suffering would be encouraged to think they deserved it somehow.

No

Not the popular bowdlerised Western form of it no.

Yes, but is only relevant if you follow a belief system which includes multiple reincarnations, which most don’t.

No, of course not, OP. In its most frequently used sense it’s just wishful thinking from people who’ve been hurt or betrayed or otherwise damaged by others, and like to fantasise about how the same fate is waiting for them. But life isn’t like a cartoon where they guy laughing at the guy who slips on the banana peel in his turn slips on another banana peel he didn’t see because he was too busy laughing at the first guy.

Nope, not in the slightest. Too many people are waiting for a good dose of it and it never seems to arrive, unfortunately.

I believe there is karma but I read a book in Thailand and it opened my eyes to the fact that karma doesn't have to happen in this lifetime, it can come in the next.

No. I mean, even apart from a point of logic and reason, do you look at e.g. chronically ill people or people who’ve experienced something like a child’s death and believe they must deserve it because they have bad karma? Because that’s essentially how it should work, isn’t it.

I believe that if you are a halfway decent, friendly, cheerful person then you’ll cultivate decency and good cheer around you and your life will go better for it. A purely human rather than superstitious effect.

Nope
If only

No, terrible things happen to good people and fantastic things happen to horrible people all the time.

I believe in....what you sow tou will reap

Not quite karma per se....more that your actions or behaviour have consequences

No, what would be the mechanism for that to operate?
