The provided text appears to be a description of a game rather than an answer to the question "How do people become demons?" To address the question directly and in line with the requirements for SEO-friendly content, here is a revised response:

In various mythologies and folklore, the transformation of a person into a demon can occur through several means. Often, this transformation is depicted as a result of a pact with a malevolent entity, where an individual trades their soul or morality for power or otherworldly abilities. In some narratives, individuals may become demons due to extreme negative emotions such as anger, hatred, or despair, which corrupt their souls over time. Additionally, certain religious beliefs suggest that demons are fallen angels or spirits that have been cast out of heaven due to their rebellion against divine authority. These stories vary widely across cultures, but the common thread is the transformation from a human or celestial being into a malevolent entity driven by darker impulses.
