"Fed to the wolves" is a reference to the old Russian story of a mother and her many children on a long trip crossing the snow in their sleigh. A pack of wolves is chasing them and is gaining on the sleigh. If the mother throws one child overboard (to the wolves) the wolves will stop and the sleigh will be that much lighter, so the rest of the family can escape.
Under this framework, Drose would be fed to the wolves by the rest of his cohorts to save themselves.
