Maximizing Loving Kindness vs Altruism ?

There seems  confusion around the term ‘altruism’ which Ayn Rand criticized. Granted, as Rand contended, something is not bad just by the fact that one does it for oneself and an action is not good just by the fact that one does it, or thinks or perceives he is doing it for others. ——–To what extent can the principle of maximizing loving kindness solve the problem associated with altruism as being either good or bad ? ————-To what extent do we allow ourselves a level of objectivity when we use ‘maximizing loving kindness’ as our standard, instead of ‘living for others’  or instead of trying to be altruistic ? ——After all, if we strive to live for others, which set of ‘others’ that does entail, and who is included and not included in our understanding of ‘others’?  What about others who are in the process of unjustly hurting people?  ———The usefulness of striving to ‘maximize loving kindness’ instead of trying  to be altruistic  may involve using the formulation of (1) striving to distinguish one’s needs from one’s wants and (2) striving to meet one’s needs with as little harm as possible and as much benefit to others as possible.
