When faced with the problem of helping an old lady cross the street, and she gets hit by a car, one may feel blameworthy. But what I want to examine is, was it the best thing to do, factoring aggregate happiness and all?
I believe it still is the best thing to do, instead of just standing there, not helping while fully capable. It's true, you have to do the best you can do, and one didn't know a car would come. It would be foolhardy to quickly run across the street and see if any cars are coming. One should be brave and trust that cars may stop when supposed to. Furthermore, that being able to trust, is an action onto itself. That trusting is taking into account the whole moral community-the lady, cars, other pedestrians, into account. Now one is taking into account the aggregate happiness for everyone, not just the old lady. Yea, its a terrible thing that happened, but what if the lady got hit without you there? Then that would be even more sad. So at least pedestrians and cars will look around and see that a positive action-helping the old lady-was preformed, and they will see how kind you were.
