What does "causal cycle" mean? What about being a man?

Everything in the world is made up of causal chains. What everyone does is a cause, what he suffers is a fruit, and this fruit becomes the next cause, and so on. This tells people to be careful what they do, and to finish well from the beginning.

Know the cause of past lives, and suffer in this life. To know the fruit of future generations, the author of this life is. Everything is a causal cycle. Gulp it off, which was decided before; No matter how big or small, there is nothing but cause and effect. You wrote everything. You directed it. Play by yourself, do by yourself, and suffer by yourself. Karma, what goes around comes around, what goes around comes around, what goes around comes around, it's not bad at all. So go back as soon as possible, plant good things and fix them. The sea of misery is boundless, and turning back is the shore. Learn Buddha and recite Buddha. Be kind, say good words, do good deeds and be a good person. We must firmly believe in cause and effect and believe in karma. "It's a foregone conclusion to drink it all at once?" !

Causality means that what you sow will be what you get. For a simple example, a person has money, so this is his fruit. He is rich because he usually works hard, which is his reason. Of course, what we usually say is "retribution". If you do something bad that hurts others, you may end up hurting yourself. This tells us that only by doing more good deeds and making more good marriages can we bear more good fruits and not do evil.

There are intrigues in society, intrigues. If causality is really an iron law, why are so many bad people not punished? Throughout the ages, there are countless such people. I don't deny this iron law, but I don't think so.

Throughout the ages, many people who have committed heinous crimes can live for a long time, but the retribution falls on their innocent families and descendants. Is this really fair? Is it against Buddhist theory? Isn't Buddhism about causality? Why did the result go against Buddhist theory?
