Health, we do chessed for the benefit of our OWN neshamos, not just to help someone else. And who are we to judge if someone frei deserves that chessed or not. Only HASHEM gets to make those determinations. There may be many zechusim that that frei person has accrued, of which you are unaware. when Hashem points us in the derech that enables us to do a tova, there is a good reason for it.
