The sinner comes out rewarded
A situation in which a sinner benefits from his wrongdoing and is not punished. An improper situation in which "crime pays."
("Whoever had seventh-year produce that came to him by inheritance or was given to him as a gift—Rabbi Eliezer says it should be given to those who eat it, but the sages say: the sinner must not be rewarded"—Shevi'it 9:9; and likewise: "The reason is that it is a fine, so that the sinner shall not be rewarded"—Ketubot 9a)
