To love or not to love

Sometimes I wonder if we should judge who are worthy of our help and who are not? The politically correct answer is of course that it is not our place to judge. Yet, sometimes after lending a hand to someone, you just feel as if you have unleashed a monster. People who feel that your help is their entitlement, people who want more than what they had asked for in the first place, people who in the end just decided that you being their crutch is the only way out for them. God commanded us to love and that is the highest order that is seemingly simple, yet perpetually unattainable. How do you love everyone? It's tough enough to love someone close to you and who loves you back. How do you love someone who is "unloveable", someone who makes loving them so difficult? I don't know. It's easy to say that we can find the good, even the tiniest bit of good, in everyone but the actually doing calls for tremendous efforts. I guess maybe I'm not trying hard enough.
