YMMV / Reverend Insanity

• Moral Event Horizon: Fang Yuan is implied to have crossed this before the novel begins, but swiftly passes this for readers early on by performing an elaborate human sacrifice for greater power and then following it up with Family Extermination for even more.
• Signature Scene: Fang Yuan feeding Gu Yue Yao Le, a fifteen-year-old girl, to a bear in order to produce Man-Beast Life Burial Gu and advance faster. While he does worse things later on, this is the first unambiguous moment where he clearly crosses the Moral Event Horizon onscreen and is widely-referenced as the series' defining scene.
