I see it more like pascals wager but instead of God fill in the blank for a lot of things.
If karma exists and rewards good people and punishes bad people, and I am good I get rewarded. If I'm bad I get punished.
If karma does not exist and it's all bullshit, and I am good. I get buying, but I don't feel bad for doing bad things and people don't see me as bad or treat me as anathema. If it doesn't exist and I'm bad nothing happens, maybe I have a conscience maybe I don't, maybe people treat me different maybe I don't notice if they do or don't.
Seems like doing good and being the good you want to see more of in the world has more good outcomes than bad🤷🏽
