Throw to the wolves
"Throw to the wolves" is an English metaphorical idiom, meaning to sacrifice someone to save or benefit oneself or one's group. "Throw to the wolves" is also sometimes used more generally to describe abandoning someone for any reason (such as some unwanted trait or property of the victim herself), cognate with "throw to the lions" and "throw to the dogs", which also derive from the supposedly man-eating appetites of a beast.
