무죄 (Innocence) refers to the state of being free from guilt or wrongdoing. In legal contexts, it signifies that a person has not been proven to have committed a crime. The presumption of innocence is a fundamental principle in many judicial systems, ensuring that individuals are treated as innocent until proven guilty. In broader terms, innocence can also describe a lack of experience or knowledge about the darker aspects of life. This concept is often associated with childhood, where individuals are seen as pure and untainted by the complexities of the world. The idea of innocence is frequently explored in literature and art, highlighting its significance in human experience.
