Judgement or Observation?

After talking with one of my brothers the other day, I was told that I was judgmental. That got me to thinking…. Am I? I know I try not to be. After all who am I to judge another person when I myself am not perfect. As an Empath, I am aware of some things that others might miss. You know. Things are constantly pinging off of my emotional guidance system.. Especially things that appear to cause others to suffer. So, how do we know when we are being judgmental or just being an observer making a comment… or discerning an experience we are witnessing, to decide where our greatest good can be applied?
