Is there retribution for hurting people with Maoshan art?

I'm not a big believer in superstition, but I believe in causal theory. No matter what way the injurer uses, there are bad seeds in his heart. Even if he is clever, there will be times when the sewer capsizes, so I think there will be retribution. To tell the truth, I know several famous Taoist priests or fortune tellers in my life. Most of their descendants are sickly or childless, and they are all under 60 years old. The reason is that they use "Maoshan technique" to save people (saving one person means harming another). Therefore, I personally advocate generosity. Nothing is a big deal. You don't harm others yourself, and you don't help others to harm others.
