Judgment towards others

[Minyatur]

So, essentially to eradicate judgment of another would require a lessening of the contrast between self and other by means of forgiveness, balancing and healing of the self? Sort of breaking down of a strong attachment to the identity of self, which would break down the seeming disparity between self and other?

I think so but I'd add faith. I think faith is important because you're not somewhere you can perceive others nor yourself whole nor can perceive the cause and effect that makes anyone act as they do or be as they are, so faith that the things you don't understand can be understood with greater awareness is probably useful for all steps above.
