How close or distant should we be when making moral judgements of others

How socially close or distant we are to other people can influence our ability to be impartial in our moral judgements of them. 

What, then, is the best placement for a moral judge? Should we strive to distance ourselves equally from everybody, or is there virtue in closeness?

 Is there even such a thing as an ideal placement for our moral pronouncements of others or do we have to embrace imperfection.v
