It would be rational for you to employ the historically felonious candidate. They would be more likely to stick with you, if only because finding a job elsewhere is hard. If lots of people did the same, wages would experience downward pressure, because the pool of possibly successful applicants would be larger. You might also do it because sometimes it pays to give someone a break.
