Karma Houdini/Oral Tradition


 * The sin-eater is a veritable karma houdini -making machine.
 * There's also the story about the knight who has to find out what women most desire. He has a year and a day to find out, or he will be executed, and eventually promises to do the next thing an old crone asks of him in return for the secret (they want power in their relationships). She demands he marry him, and it turns out that she can make herself young and beautiful again. He lets her choose whether she will be beautiful in the day or night(or, depending on the version, beautiful and unfaithful, or old and true), and in return gets a beautiful wife all the time. Why did he have to find out what women most desire? He raped a girl, and in return gets a beautiful wife for it. There was absolutely no other punishment besides "find out what we want most and you can live."
 * It may not be the origin, but that story was included as the Wife of Bath's tale in The Canterbury Tales. For extra ridiculousness, the one who offered the knight the most insane pardon for rape ever was the Queen. The King just wanted him killed.
 * It wasn't quite that simple, he would be killed in the end if he couldn't figure out what women want. After searching and asking many women, who all gave him different answers, is when he found the crone. I believe she tricked him into marrying her and gave him the choice when he was presented to the queen again, where he gave her his answer, . Because he recognizes the will of the crone she and the queen forgive him, so the crone will be a crone by day, but at night turn into a beautiful woman for him and also stay true.
 * Any story involving The Fair Folk.
 * In Greek Mythology, the goddess Nemesis was all about preventing Karma Houdinis. In fact, she was the goddess of karma.
 * Though the Greek Gods themselves are apparently exempt from Nemesis' Karma. As long as they don't offend a god that's more powerful then them, (which to this troper's knowledge they never do) any of the Greek Gods can do whatever they want to both each other and mortals. Neither other Gods or especially mortals are able to do anything about it. In fact, if a mortal is involved in the slight, even if it's not their fault, such as say with Medusa or the various women Zeus has cheated on Hera with for example, it's the MORTAL rather than the God gets punished.
