Moral Degeneration

Moral degeneration is a trope tag for stories where a character's values, principles, or sense of right and wrong erode gradually as an outside force, such as corruption, addiction, blackmail, or repeated temptation, chips away at their original standards. Unlike a single corruption event, this tag emphasizes the slow, cumulative slide rather than one turning point, and it's frequently used alongside netorare or slave-themed doujinshi. It's a favorite framing device for long-form character-transformation manga. Stories tagged this way are searchable within Top Hentai's moral degeneration hentai section.
