Much as we try not to be judgmental, but could we? It is like the yes and no the i and the o, every moment in life we have to make a judgment, good or bad, ugly or beautiful, smart or stupid, right or wrong, but do we need to be judgmental.
I think we cannot escape from being judgmental.
By all means do so, the most important thing to do is to be fair, to be just in our judgment.
Do we need to judge all the time? Why bother? why add the burden of judging? so by all means judge, but only as necessary.
Then there are judgment related to moral and personal. Only to those whom you are morally and personally responsible off course, otherwise you are not being fair and just.
