(Some thoughts on how to meet another person, and to view each other.)
They say that love is blind, and there is some truth to that. Love keeps no record of wrongs. That is why love can see good things in another person that a less sympathetic view will overlook. If love keeps no record of wrongs, on the other hand hatred takes no notice of the good that has been done.
Of course there are other options besides those two. Indifference overlooks good and bad together. But what about a determined, impartial scrutiny to weigh the good and the evil in another person? Wouldn't that give us the clearest view? The clearest view of what, exactly, though? That approach sets us up as the judge. Are we that sure of our own impartiality? Are we that sure of our own purity and wisdom? Does the lack of humility there weigh against such self-confidence? What about the lack of compassion? And would we want others to view us so unsympathetically? Do we owe anything to our shared humanity to take a kinder view as a starting point, rather than to meet another person with a determination to weigh them in the scales before we recognize their worth? Do we owe anything to the Lord who made them, to the image of God within them, to trust that within them is the potential to be that child of God, as good as we are if not better?
When we have to choose an approach to another person, the wisest approach is love, and the humblest approach is love, and the kindest approach is love. The one that gives us the clearest view of any good in the other person is love. And the most constructive approach -- the one that helps build up the other person -- is love.
