罪恶 (Sin) refers to actions or thoughts that are considered morally wrong or in violation of divine law. Different cultures and religions define sin in various ways, often associating it with the idea of wrongdoing against a higher power or ethical standards. In many belief systems, sin can lead to spiritual consequences and is often seen as a barrier to achieving a good life or afterlife. In Christianity, sin is often categorized into two types: mortal sins, which are serious offenses that can lead to separation from God, and venial sins, which are lesser wrongs that do not sever one's relationship with the divine. Other religions, such as Islam and Buddhism, also have concepts of sin, emphasizing the importance of moral conduct and the impact of one's actions on oneself and others.
