When a character is tempted to do a Face Heel Turn or a Heel Face Turn, it is often the result of much Character Development in their lives, forcing them to weigh their nature, goals, loves and even hates in balance. It is by no means a simple or trivial matter, so we here at TV Tropes have decided to make discovering the likelihood of such an event for a character simpler. But since we already have a All the Tropes Wiki Drinking Game, we decided to make it a sorting algorithm instead!
