The idea of tying the concept of care exclusively to duty is fine perhaps within a legal context, but not so fine (inadequate as well as inappropriate) when it comes to a personal-ethical situation. For in the latter, care is not just a question of paying back a debt that is owed or meeting an obligation.
Thus when caring for a loved one, such as an elderly parent for example, then to care is to grieve or to mourn their frailty and the fact of their immanent passing (their mortality); in Lawrentian terms, one might say to care is to assist another in building their ship of death.
Thus Heidegger was not far off the mark when he linked Dasein's being in the world both to Sorge (care) and to Sein-Zum-Tode (being-towards death).
