Integrating my judgemental side (Shadow work)

I've recently realized via therapy that many of my fears about others' judgements of me are actually Shadow projections of my own judgement toward others. This is leading me to the conclusion that I need to learn how to accept my "judgemental side." This is hard because I generally think of judgment as an unhelpfu, relationally ineffective activity. I wonder if you all might be willing to reflect with me on some of the "positive" or useful functions of judgement, in order to help me work toward acceptance. I'll try not to judge your answers too harshly ;)
