It is a great sin to slander Buddha and law, but Buddha and Bodhisattva are not angry, because they have long lost greed and ignorance. Also, it must be understood that they are rewarded because of the law of causality, which is inherent in the universe, not decided by buddhas and bodhisattvas, nor for revenge. We believers may be angry if we don't have enough spiritual skills, but we shouldn't be angry. Anger is anger. You know, all living beings have Buddha nature, and the essence is Buddha. We just lost our nature for a while, were confused by fame and fortune, and didn't know the truth, so we should pity them for committing such a crime, because they will be very painful in the future. We should practice seriously and carry forward Buddhism.
It's rare that you have the heart to protect Buddha, Amitabha. I recommend two books for you, which are suitable for your first contact with Buddhism: Realizing Cause and Effect and Feeling the Sea. After reading these two books, you will understand a lot. If you have any questions about Buddhism, you can ask me, and I am willing to answer them for you. Amitabha, I hope you can enter my Buddhism, break the mystery and be enlightened.
